  1. Top 5 Benefits of Fiberglass Rebar in Flatwork

    Comments Off on Top 5 Benefits of Fiberglass Rebar in Flatwork

    Concrete flatwork is foundational for everything from sidewalks and driveways to industrial floors and commercial slabs. While traditional steel rebar has long been the go-to for reinforcing these flat surfaces, its drawbacks include susceptibility to corrosion, heavy weight, and higher labor costs. These drawbacks explain why builders and contractors are turning to fiberglass rebar, also known as GFRP rebar, to reinforce flatwork concrete more efficiently and effectively.

    GFRP rebar is a lightweight, corrosion-resistant alternative made from fiber-reinforced polymers. It’s quickly becoming a staple in modern construction. When used in flatwork foundations, it provides exceptional durability, reduces long-term maintenance costs, and simplifies installation. This article will explore why GFRP is a preferred material for flatwork.

    Traditional Rebar Challenges in Flatwork Foundations

    Steel rebar is strong but has vulnerabilities in concrete flatwork exposed to moisture, salt, or chemicals. Over time, steel can corrode, leading to:

    • Concrete spalling
    • Structural weakness
    • Costly repairs

    The material’s weight also makes it labor-intensive to install, and steel’s thermal expansion can cause internal stress in concrete, leading to cracks over time.

    How Fiberglass Rebar Solves These Issues

    Fiberglass rebar eliminates many of the downsides associated with steel. It won’t rust or corrode, even in extreme outdoor environments. It’s about one-third the weight of steel, making it easier to transport and install. With a thermal expansion rate close to that of concrete, GFRP significantly reduces the risk of cracking due to temperature fluctuations.

    Let’s explore the top five benefits of using fiberglass rebar in flatwork applications.

    5 Benefits of Fiberglass Rebar in Flatwork

    1. Cost-Effective Alternative to Steel Rebar

    The lightweight nature of fiberglass rebar also translates to lower shipping costs and faster on-site installation. Contractors can often complete jobs faster when they use GFRP, which decreases labor hours and speeds up project timelines.

    The long-term savings are substantial. You can save on maintenance and repairs over a longer service life.

    2. Corrosion Resistance for Long-Lasting Durability

    Steel rebar deteriorates when exposed to moisture, de-icing salts, or chemicals—especially in outdoor or industrial flatwork applications. Over time, this rust compromises both the rebar and the surrounding concrete.

    A significant benefit of GFRP is that it does not rust. Its corrosion resistance makes it ideal for long-term installations in driveways, patios, walkways, and foundations exposed to the elements. This durability significantly extends the life of the concrete flatwork.

    3. High Tensile Strength with Lightweight Handling

    In addition to being much lighter than steel, GFRP rebar offers impressive tensile strength, up to 4.5 times stronger in some cases. This high strength-to-weight ratio means GFRP rebar performs better and is easier to handle on-site.

    Because it’s lightweight, fiberglass rebar can lower transportation costs and speed up installation, which is particularly helpful in large-scale concrete flatwork projects where labor and time efficiency matter.

    4. Reduced Thermal Expansion and Crack Prevention

    Steel expands and contracts at a different rate than concrete. This mismatch causes stress within the slab, often leading to unwanted cracks, especially in regions with significant temperature swings.

    Flatwork fiberglass reinforcement is thermally compatible with concrete, meaning both materials expand and contract at similar rates. This reduces internal stress and helps preserve the integrity of flatwork foundations over a longer period.

    5. Chemical Resistance for Harsh Environments

    In industrial and coastal settings, exposure to harsh chemicals or salt accelerates steel corrosion, which can compromise structural stability.

    GFRP rebar is resistant to a wide range of chemicals, making it ideal for warehouse floors, chemical plants, parking garages, and any other flatwork concrete exposed to aggressive environments.

  2. Month End Rebar Comments – May Scrap Update

    Comments Off on Month End Rebar Comments – May Scrap Update

    Scrap posted late last week, down $40/ton from April for its second consecutive monthly decline. The Chicago index finalized at $380/ton, giving back the majority of its gains from Q1. We entered 2025 with Chicago shredded scrap at $360/ton. In May we are now only $20/ton higher than where we began the year. Although domestic rebar mills are tight on supply to begin the month & steel products in general still have very solid demand, rebar producers will face mounting pressure to consider the decline in raw material costs as we move forward into the spring season.

    We will continue to keep you updated on developments in the rebar market.

    Have a great week.

  3. Month End Rebar Comments

    Comments Off on Month End Rebar Comments

    As April draws to a close, it is evident now that the rally that began in February has peaked or, at the least, paused for the time being heading into May. Fueled by rising scrap costs and tariff threats, the rebar market saw 2 increases totaling $70/ton pushed through in Q1. Some clarity in the rebar market is beginning to emerge. Scrap is beginning to retreat from its recent highs. Tariffs on rebar have proven to be less impactful to the overall rebar market as they have been on many other steel products. Supply is still tight and here till now… pricing has stabilized, but concerns are developing on the horizon with regards to holding current rebar pricing.

    On the scrap front… 3 months of increases to start 2025 totaled $100/ton. Last month scrap retreated $40/ton, and indications of a similar decline for May are beginning to circle. More conservative estimates mid-month of smaller declines have since given way to more aggressive, larger declines in shredded scrap for May. The final should come out next week, but it is likely that a good portion of the increase will have been reversed heading into May. Shredded scrap is showing the least signs of strength in the raw materials as shred supply at dealers is outweighing current mill demand, and there are little to no export opportunities to help relieve. Other grades, such as prime and heavy melt, are still holding firm, with demand for finished goods in those markets holding firm and creating strong demand from the mills in other raw materials products.

    Domestic rebar mills remain very tight on inventory in most all regions. While it has improved somewhat throughout April, several mills around the country still have holes in inventory on key items. The tightness in supply is helping to keep pricing in check as inventory in the supply chain is also very low given the time of the season heading into the busiest months. It is likely that the trend will continue through May and serve well to help resist the urge of falling prices…. While the mills are seeing the signs of a softening market, they really are not faced with any panic until they have excess inventory that needs to sell.

    On the import front, offers are few and far between, but the pricing does show value compared to current domestic pricing. Threats from the administration related to the shipping industry and Chinese vessels have importers wary of finding ways to transport products purchased overseas. The result is many have chosen to sit on the sidelines for the time being until the picture becomes clearer. This is only helping to tighten the supply picture in the states and keep inventory in check. The few offers that are out there are in line with import pricing that began the year but are currently targeting August and September arrivals. Most prefer to wait and see what the domestic market will do between now and then.

    We will continue to update you with details related to the rebar market. Have a great rest of the week and start of May.

  4. Scrap Finalizes & Tariff Update

    Comments Off on Scrap Finalizes & Tariff Update

    Yesterday afternoon, Chicago shredded scrap was finalized at $420/ton, down $40/ton from March. A decline was expected for the month, and the $40/ton was on the higher side of what had been predicted to start the trade. The drop reverses a 3-month run of increases to start the year that saw a total of $100/ton in increases. Today shredded scrap sits $60/ton higher than where we ended last year, and domestic mills current pricing in the market reflects a similar premium. Expectations for the coming months are a sideways to softening raw materials market, which will undoubtedly be in the back of the minds of the domestic mills as they navigate forward.

    On the tariff side, rebar has been spared from much of the drama that has played out over the last 2 weeks. More impactful on the rebar market was the Administration’s “proclamation” in February closing all the loopholes in the Section 232 tariffs that have been in place since 2018. Those measures are already in place, as recently reported. Last week, when the administration first announced reciprocal tariffs, they specifically excluded steel & aluminum from those reciprocal tariffs, rather defaulting to the 232 measures that were in place previously. Consequently, yesterday’s “pause” on many reciprocal tariffs again had little direct impact on the rebar market moving forward.

  5. The Complete Buyer’s Guide to Construction Materials

    Comments Off on The Complete Buyer’s Guide to Construction Materials

    Material selection is an essential step when completing any type of construction project. The materials should provide durability, structural integrity, and dependable performance while remaining within your budget and meeting design requirements. With so many options available, you might need some help making the right choice before you order materials. This guide details the different factors to weigh during construction material selection (like quality considerations and how to estimate construction material costs for your project) so you can choose the material that meets your building requirements.

    Considerations When Choosing Construction Materials

    There are several factors to consider with construction material selection, including:

    Durability

    Short- and long-term durability are essential considerations, as the local climate could greatly impact the integrity of materials. If you need materials for temporary construction, for instance, the long-term effects of elements like moisture and corrosion won’t likely factor into your decision. Conversely, for more permanent structures like warehouses, storefronts, and tall buildings, you will need to ensure that the materials you choose can hold up in the given environment.

    Cost

    Another factor to think about is the cost of materials. Structural requirements will also influence this aspect, as permanent structures will generally require durable, long-lasting materials than those used in temporary construction, which may only need to last a few weeks. You’ll want to compare the cost of different material types and sizes: for example, thicker and longer rebar will generally cost more than their smaller counterparts. Likewise, stainless steel can cost more per linear foot than plain, untreated steel.

    Availability

    Trying to source hard-to-find materials can be time-consuming and can also lead to higher procurement costs. If the ideal material option isn’t readily available in your area, you may want to consider viable substitutes to help you stay on budget and on time. The right materials manufacturer can help you choose suitable replacements based on your specifications.

    Level of Maintenance

    Maintenance is often necessary to keep structures in good shape after initial construction is complete. However, the amount of maintenance and repairs they require will depend largely on the quality of the materials you choose. While opting for cheaper materials can lower initial costs, those materials may require constant attention over the structure’s life, leading to higher maintenance and repair costs. Higher-quality materials, however, will generally require less maintenance over time.

    Sustainability

    A growing number of businesses consider sustainability when choosing materials for their application, and the construction industry is no exception. Contractors must think of ways to keep construction projects environmentally conscious and determine the potential impact of the materials they work with. They can also work to ensure that permanent structures can meet sustainability goals long after construction.

    While you may not be able to incorporate sustainable materials into every aspect of construction, you can still take steps to make the project as environmentally friendly as possible without compromising integrity. This could mean choosing a material that does not rust, meaning it doesn’t release harmful chemicals into the environment. It could also mean using lighter-weight materials to reduce the environmental impact associated with transport and handling.

  6. Rebar Market Comments

    Comments Off on Rebar Market Comments

    As the rebar market enters Q2 of 2025, some patterns are beginning to emerge. While other steel products continue to rally in price, rebar appears to have leveled off with consumers gaining confidence that supply will support demand moving forward. The $100/ton in scrap increases in the first quarter have only been able to support $70/ton of increases from the steel mills in the first quarter. While other steel products have experienced price hikes of 4-5 times that amount, rebar has remained rather conservative. Still, the increases have created an active market in Q1, and as we begin the second quarter, supply remains tight at the domestic mills, and overall inventories are minimal.

    Domestic mills were able to keep up with stronger Q1 demand in the rebar market, albeit they had to deplete most all on-hand stock in doing so. Now with the higher market prices, the pace of new orders has slowed somewhat, allowing mills to have space on rollings, catch up, and once again have some breathing room moving forward. There is not a lot of material on hand at most mills to begin April, but with most outages now in the rearview, mills have growing availability for the months ahead. Mills are pushing to maintain pricing but are starting to see pressure from both import pricing as well as signs of a scrap market that may have peaked and is beginning to retreat. Mills will weigh the strength of their order books to try and resist the calls to reduce pricing.

    On the import front, pricing has begun to gain traction with the gap between domestic and import increasing over the first quarter. However, import supply still faces challenges. The political discussions involving tariffs and retaliatory tariffs as well as potential trade hurdles levied on the shipping industry have increased the risk of bringing in imported products. Higher prices are being offered in most cases to offset these risks. Unfortunately, those higher prices reduce the price gap and reduce the attractiveness of the offers. As a result, offers on imported material have slowed heading into the 2nd quarter. There will be some imported products arriving in the months ahead, but the volumes currently look to be controlled, and the pricing is up somewhat from where we started the year.

    On the scrap front, after a 3-month run of increasing prices, April looks to potentially show signs of a plateau and quite possibly a backslide. The strength of the entire steel sector undoubtedly helped fuel shredded scrap prices higher and sustain the raw material rally longer, but signs of fatigue are starting to emerge. Ample supply of shred is now available heading into April. At the same time, mills have curtailed their demand for the product in the months ahead, putting some downward pressure on the prices. Dealers are getting little help from the export market as global prices are much lower than the pricing in the states, forcing them to only find homes in the US market. There is a strong likelihood scrap prices will soften for next month. Most believe that the market will give back most, if not all, of the March gain of $30/ton back in the April trade. It is still several days away from posting and subject to change. I will update when it does post.

    In the meantime, have a great start to April. Spring is right around the corner!!!
