Congrats, Western Extrusions: first EPDs go live

What Western Extrusions just published

Western Extrusions debuted its first wave of Environmental Product Declarations in May 2025. Thirty‑two current EPDs cover three core conduit families used under MasterFormat 26 05 33.13: Electrical Metallic Tubing (EMT), Intermediate Metal Conduit (IMC), and Rigid Metal Conduit (RMC). The set spans common trade sizes from 1/2 inch to 6 inch, plus family‑level declarations that group SKUs where the rules allow.

In plain terms, this is a spec‑ready footprint for the conduit aisle. It meets what estimators, engineers, and owners want to see when embodied‑carbon accounting shows up on the kickoff call.

Why this matters in specifications

On projects that require whole‑building LCA, a product without a product‑specific, third‑party verified EPD forces teams to model with conservative defaults that can penalize selection. Showing up with an EPD keeps the product in play on criteria that go beyond price. It also reduces back‑and‑forth during submittals, since the data is already verified and formatted for comparison.

Think of the PCR as the rulebook and the EPD as the box score that fits on the stat sheet. Western Extrusions now has both in hand for its conduit portfolio.

Competitive snapshot

The conduit category is active on transparency, and Western Extrusions just joined the arena.

• Atkore publishes product‑specific EPDs across galvanized EMT, IMC, and RMC, plus stainless and PVC. Documents in that set run through Smart EPD and have been live since 2024.
• Wheatland Tube also publishes EPDs for IMC, RMC, and EC&N components. Their recent documents sit with UL and align closely to what engineers buy for commercial work.
• Picoma has an EPD focused on fabricated steel elbows. Useful for fittings packages, though not a full conduit family.

Against that backdrop, Western Extrusions now matches category expectations on EMT, IMC, and RMC coverage, with breadth across sizes that specifiers actually call out on schedules. That shifts conversations from “do you have an EPD” to “does your EPD fit this job’s scope.”

Program operator and LCA partner

Western Extrusions’ EPDs are verified and published with UL Solutions as the program operator. The developer of record listed is WAP Sustainability. For buyers, that pairing signals a familiar verification workflow and a document format many plan reviewers already recognize.

For context on operator fit, Smart EPD is also widely used in U.S. electrical categories and appears on many conduit declarations, including competitor sets (Smart EPD, untangled). Choosing an operator your market checks first is a small decision that can save weeks of back‑and‑forth during verification.

Where to find the documents

As of today we could not locate the new EPDs on westernextrusions.com under News or Resources. Visibility matters, since specifiers often start on a manufacturer’s website before searching databases. Our take is simple. Add an easy‑to‑find Sustainability or Resources page and post each PDF with product family names, plant scope, and issuance month. That reduces friction and prevents avoidable email chases. It’s a quick win and it’s definately worth it.

What buyers will notice

• Product‑family scope where the rules permit, with size coverage that matches common trade sizes for EMT, IMC, and RMC.
• Clear alignment to MasterFormat 26 05 33.13, which helps estimators slot the documents into bid packages without guesswork.
• A publication month that is recent enough for emerging owner requirements and LEED v5 minded design teams.

Teams prize speed and completeness during submittals. Having EPDs across the full conduit set means fewer gaps and faster approvals.

A short note on timing and renewals

Western Extrusions launched a coordinated set in the same month. That helps internal teams standardize messaging and sales playbooks. Track PCR updates and keep an eye on renewal windows so future waves stay aligned with current rules. Publishing in batches can also keep verification calendars predictable for busy seasons.

Takeaway for manufacturers

This is a textbook first move. Pick a high‑volume category, align on the common PCR, publish with a familiar operator, and cover the size range that schedulers actually buy. Competitively, it catches Western Extrusions up to brands that already use EPDs in the conduit aisle and makes room to win specs where a verified declaration is a hard requirement. The transparency arena just got another serious player.
