  2. The Rise of GFRP: When to Swap Steel for Fiberglass Rebar

    Comments Off on The Rise of GFRP: When to Swap Steel for Fiberglass Rebar

    Glass Fiber Reinforced Polymer (GFRP) rebar, also known as fiberglass rebar, is a type of synthetic rebar made from a polymeric resin and strengthened with continuous glass fibers. While traditional steel rebar has been used for over a century to reinforce concrete structures and improve their structural integrity, fiberglass rebar has become an increasingly popular alternative to steel in recent years due to the numerous advantages it can provide. In particular, GFRP is favored due to its enhanced strength-to-weight ratio, corrosion resistance, and sustainability.

    If you’re unfamiliar with GFRP rebar, you may find yourself wondering when you should swap steel for fiberglass rebar. Keep reading as we explore the advantages GFRP provides over steel, and when you should choose it.

    When To Use GFRP

    While fiberglass rebar has been around for decades, it has seen a steady rise in popularity over the last few years, particularly due to its corrosion resistance. A few instances where GFRP rebar is preferred include:

    • High corrosion environments. GFRP rebar is ideal for high corrosion environments such as coastal, marine, and chemical plant applications where saltwater or industrial chemicals would cause steel to rust and expand, destroying the concrete structure.
    • Non-magnetic/non-conductive material is required. Fiberglass rebar is also ideal for use in areas where non-conductive materials are required, such as MRI rooms, laboratories, and electrical substations.
    • Weight sensitivity. GFRP rebar should also be used in applications where material weight is a concern. Since fiberglass rebar weighs up to four times less than steel, GFRP is the ideal choice for projects that require lightweight materials. Fiberglass is also preferred when working with smaller crews, as it is easier to handle.

    Benefits of GFRP Over Steel

    When deciding whether to use steel or GFRP rebar, you’ll have to consider the pros and cons of each option. While steel rebar has traditionally been the product of choice, GFRP has been shown to provide several key benefits over steel rebar, including:

    • High strength-to-weight ratio. While GFRP is significantly lighter than steel, it also has a higher tensile strength. This makes it an extremely efficient choice that can ensure long-term structural integrity of your building and reduce transportation costs and construction time.
    • Long-term cost efficiency. Fiberglass rebar requires less maintenance and repairs, and it can last up to three times as long as steel. GFRP is then a better long-term investment than steel rebar.
    • Low environmental impact. As green building projects become more popular, this has led to an increased demand for fiberglass rebar, as GFRP production has a lower carbon footprint and requires less energy consumption than steel.

    Significant Upfront Savings: A Cost-Effective Steel Alternative

    One of the most persistent myths in the construction industry is that GFRP is always more expensive than steel. In reality, modern manufacturing advancements have made fiberglass rebar significantly less expensive than steel for many applications. When you factor in the current market volatility of steel prices, GFRP offers a stable, budget-friendly alternative that can lower your initial material spend.

    Beyond the price per foot, GFRP delivers immediate upfront savings through:

    • Reduced Freight Costs: Because GFRP is up to 75% lighter than steel, you can ship significantly more material per load, slashing transportation expenses.
    • Lower Labor Costs: The lightweight nature of fiberglass allows crews to move, place, and tie the rebar faster and with less specialized heavy equipment.
    • No Premium for Protection: Unlike epoxy-coated or stainless steel rebar which carry heavy price premiums to fight corrosion. GFRP is naturally corrosion-proof at a fraction of the cost.

    For contractors and developers looking to protect their margins without sacrificing performance, swapping to GFRP is often the most fiscally responsible move from day one.

  3. Scrap Posts Final

    Comments Off on Scrap Posts Final

    Chicago shredded scrap posted final today for March at $450/ton…. No change from February. The non-movement was expected in recent weeks as scrap flows improved with the weather throughout much of the country. Mills are likely going to try to maintain current pricing moving forward, as they will face some headwind with import arrivals and an improving overall supply picture. The non-movement in scrap will help their argument. Expectations for scrap moving forward are likely downward pressure in the months ahead, and mills will be satisfied if able to hold the line on price for the time being.

    We will continue to keep you posted on developments that affect rebar. In the meantime, have a great weekend!

     

  4. Rebar Market Update

    Comments Off on Rebar Market Update

    As March begins, the rebar market remains strong in several regions. While terrible weather plagued much of the East Coast in February, that was not enough to deter sentiment throughout the entire country, with most regions reporting solid demand, tight but adequate supply, and a solid backlog moving out of the winter season. Throwing in some pent-up demand from the East Coast after the seasonal stall, most view the rebar market as very bullish heading into the spring months. Recent events in Iran as well as the ruling by the Supreme Court on tariffs earlier this month are expected to have little impact currently on the rebar market, neither positively nor negatively.

    On the domestic side, pricing remains high after the January price increases are fully in play. In some regions the price is facing headwinds, especially those where weather has been a factor. As a result of the pressure on the January price increases, mills have yet to increase pricing from the February scrap price bump of $30/ton. Rather, they are looking to create price stability in the face of upcoming import supply pressure as well as domestic capacity increases that are now helping to grow the overall supply picture. In general, lead times have reduced, and mills are now back to more normal lead times on rebar with their rolling despite still being sold out on upcoming rollings.

    On the import front, foreign mills are looking to increase pricing from offerings 30-60 days ago. The pressure of 50% tariffs and rising freight costs are pushing the transactional prices up. With domestic mills holding the line on pricing in February, the import increases are failing to garner attraction from US buyers for this go-around. As such, there has been a lull in new bookings in the latter part of February, and expectations are that the summer import arrivals will plateau after an initial bump in import arrival volumes to start the season.

    On the scrap front, upward pricing on scrap appears to have paused. The weather that negatively impacted collections is now facing the inevitable improvement with the shift heading into spring. While most do not expect a big change for March, the longer outlook looks to be heading down into spring. This trend is not uncommon in the steel market, with rising scrap in the winter due to tight collections, followed by an easing in the spring. 2026 appears to be following that trend. We will update you when scrap does post the final to start in March.

    In the meantime, have a great start to the week and the month!

  5. Scrap Update – Post Final

    Comments Off on Scrap Update – Post Final

    Chicago Shredded Scrap posted the final yesterday for February at $450/ton, up $30/ton from January, bolstered heavily by tight collections in January due to weather. The upward move is the 3rd consecutive month of increase, totaling $80/ton in the 90-day span. The move is not unlike last year’s spike, which saw a $90/ton increase over 4 months to start the year. History suggests that this may be the peak of the run, and this latest bump was related largely to severe weather that plagued most of the US to start the year. Most expect March scrap to be sideways or possibly even begin a retreat. As such, mills appear to be hesitant to try and push pricing higher, especially in the face of import offers and an increasing domestic rebar supply. Mills have only started to realize January price gains, which curbed the intake of new orders and drove buyers to consider import offers that remain consistent. Many feel a follow-up move would have a similar and stronger reaction in the market. We will continue to monitor any news that impacts rebar and report events that affect the rebar market.

    Have a great week!

  6. January Rebar Notes

    Comments Off on January Rebar Notes

    Demand continues to be solid in the rebar market as January comes to an end, while at the same time supply is showing signs of noticeable improvement. There was a mill price increase announcement in January of $30/ton, which was beginning to take effect as we rolled into February. The price increase has not gained in all regions as of yet, but it remains in the discussions throughout the country. Scrap continues to show strength, aided by very difficult weather conditions in January, while imports continue to gain traction with the domestics pushing pricing higher. By most accounts January was a strong month to start 2026.

    On the domestic side, most all mills still remain busy. Order books are full, and many mills are still “allocating” their tons from each cycle. However, most agree that the tightness the market saw in October and November has now subsided and the tons that the mills are supplying are able to meet the demand in what is typically a slower month. Items that previously had a 4–6-week lead time might now be on hand, or at worst, buyers will have to wait 2–3 weeks until a sourcing option opens availability. Mills remain busy enough to push a price increase narrative but are well aware that overall rebar supply may outpace demand moving forward.

    On the import side, imports have gained traction in the market. While domestic mills looked to raise prices in the US in January, the global market remained flat. As such, the gap between import prices and domestic ask prices grew last month.  With a growing value proposition for imports and heading into the springtime, several buyers appear to have taken advantage of future supply availability at fixed pricing. Look for import volumes to increase in the months ahead with rumors of multiple shipments concluded for Q1 production overseas for the states.

    On the scrap side, January winter conditions gripped pretty much the entire country disrupting scrap flows and reducing supply. As such, scrap dealers are pushing a higher price narrative for February. Mills are quick to point out that the tight supply is weather-related and temporary. As such, mills are fighting the increases for this month arguing consistent demand. The majority expect another bump of $20/ton (+/- $10/ton) for February, which would mark the 3rd monthly increase. Trade begins today, and scrap will likely finalize close of business this week or early next week. We will update where it finally settles.

    In the meantime, have a great start to your week!
