Congrats, MST Rebar—first EPDs on the board
MST Rebar Inc. just put verified numbers behind fiberglass rebar. In June 2025 the company debuted its first family‑level Environmental Product Declarations for structural and bent GFRP rebar, giving specifiers a clean, comparable data point instead of generic stand‑ins. That shifts conversations from “can we model this” to “does it fit the job,” which is exactly where sales teams want to be.
What launched in June
MST Rebar published two product‑specific EPDs covering its core fiberglass rebar families: structural rebar and bent bar. The declarations are issued with the International EPD System under the EN 15804 A2 framework using PCR 2019:14 v1.3.4. The LCA and documentation were developed by inti APAC. Scope reads as product‑family, not a one‑off SKU, which is what most submittals expect for rebar packages.
Why this matters in specs
GFRP rebar shows up where corrosion risk is real and where default factors can skew whole‑building LCA models against teams without product‑specific data. With current, verified EPDs, project tools stop penalizing by assumption and start comparing on actual impacts. The broader trend backs this move. The International EPD System reported more than 18,000 valid EPDs with record publications in 2025, a clear market signal that transparency is now table stakes (EPD International, 2025).

Where MST Rebar now stands competitively
Pultrall’s V‑ROD portfolio has product‑specific EPDs that cover straight and bent bars, so MST Rebar now meets the same visibility bar in composites. Owens Corning’s PINKBAR also lists a product EPD for GFRP rebar, which shows up regularly in submittal sets. Mateenbar publishes EPDs for fiberglass rebar and related forms in several regions. Net result, MST Rebar has entered the transparency arena alongside the names most spec teams already know.
Commercial takeaway for bids
When owners or designers ask for verified impacts, not having an EPD forces conservative defaults that can nudge products off the shortlist. These two family‑level documents keep MST Rebar in play across corrosive and EM‑sensitive applications where GFRP is already a technical fit. The move also reduces submittal ping‑pong because reviewers can cite a third‑party verified source instead of chasing spreadsheets.
Can buyers find the EPDs on the website today
We could not locate an EPD download page on mstbar.com at the time of writing. Visibility is key for bidding velocity, so the next low‑lift win is a dedicated EPD landing page linked from Products and Resources with direct PDF links. That page should also note the rule set used, reference year, and who verified the documents. It will definately cut down on “send me the EPD” emails.
What smart teams copy from this play
Publish where your buyers already look. Use the same PCR credible competitors use so results compare cleanly. Frame scope at the family level so one declaration covers real‑world schedules. Keep reference‑year data tidy and plan a renewal calendar early so these advantages do not lapse at the wrong moment.
Bottom line
MST Rebar’s June release puts fiberglass structural and bent bars on the record with verified numbers. That catches the company up to the composite rebar brands most visible in specs and gives design teams fewer reasons to swap late in design. It is a practical, market‑ready upgrade for any GFRP supplier competing on value rather than assumptions.
Frequently Asked Questions
Which MST Rebar products are covered by the new EPDs?
Two family‑level EPDs cover fiberglass structural rebar and fiberglass bent bar, aligned to EN 15804 A2 under PCR 2019:14 v1.3.4.
Who issued and who developed MST Rebar’s EPDs?
Issued with the International EPD System, developed by inti APAC, and verified to EN 15804 A2 rules.
When were the EPDs released?
They were published in June 2025 and are current as of today.
How does this change MST Rebar’s competitive position?
It puts MST Rebar alongside Pultrall and Owens Corning on EPD visibility for GFRP rebar, with Mateenbar also active in several regions. That removes a common submittal hurdle in specs that require product‑specific EPDs.
Where can specifiers download the EPDs?
We did not find a public EPD download page on mstbar.com today. Adding a dedicated page with direct PDFs and rule‑set notes is recommended for faster submittals.
