7 Steel Sections (Merchant Bar)

Name: 7 Steel Sections (Merchant Bar)
Brand: 7 Steel UK

Hot-rolled merchant bars and structural sections (angles, flats, shapes) for steel frames and secondary structure. Cardiff electric-arc-furnace steel from recycled scrap. The EPD declares 482 kgCO2e/tonne at A1–A3, and assesses an end-of-life recycling benefit as module D — a scenario outside the A–C boundary, not a credit against the product stage.

* EPD transport and installation scenario, not this project's. Not declared: site, use. Module D shows potential impacts or benefits from reuse, recovery or recycling after the product's assessed life. It is reported separately and never added to A-C. Do not compare bar lengths between materials. Each chart may use a different scale and declared unit.

* A4/A5 are EPD scenarios, not project-specific results. Module D is outside the A–C system boundary and is not added to A–C. Module nomenclature follows BS EN 15978 / EN 15804. Declared values are suitable as inputs to a whole life carbon assessment under the RICS Professional Standard (2nd edition); this panel is not an assessment.

Comparison Status

The record contains the basic metadata required for a controlled comparison. Products must still perform the same function and use compatible units, PCRs and lifecycle scope.

Design & Specification Notes

Qualitative notes for early design discussion. Not product-specific EPD evidence, and not a basis for numerical comparison.

Hot-rolled merchant bars and structural sections (angles, flats, shapes) for steel frames and secondary structure.

Typical Uses

•Primary frame
•Long-span elements
•Load-bearing supports

Key Performance

High load-bearing capacity for primary frame.

Typical Service-Life Estimate

60 years

Generic estimate for early design discussion; confirm with the manufacturer.

Specification Actions

•Confirm the current EPD covers the selected steel product and manufacturing route.
•Verify recycled content and the steel manufacturing route with supplier evidence.
•Calculate transport distances for primary materials.

Indicative Health & Indoor Air

low Risk

Inert steel; standard hot-works/handling precautions on site.
