Specifier’s Evidence Scorecard for Crate Suppliers
Tick what a supplier can actually hand you. The score tells you how much of the structural argument you would be signing on their behalf. Run it on Storm Manage too — we score ourselves in public further down.
Part 1 — The Four-Question Load Test
Applies to every load claim on their datasheet
Part 2 — The Evidence Pack
Documents to request before the design is signed

Score the supplier
Tick every item the supplier can evidence today, not the ones they say they could get.
How Storm Manage scores on its own scorecard
We score 68 / 120. We can evidence the kN/m² rating, the test standard reference, the vertical and lateral short-term data, the installed-orientation values, and a clear approval statement. Our published figures name the lab, the report number and the temperature conditioning.
We cannot yet tick two: the EN 17151 long-term creep report, and third-party approval (BBA / Kiwa / WRc). That is the honest position, and the reason the checklist exists. Ask every supplier for both — and notice how many of the datasheets you are comparing simply do not mention them.
Scoring is a procurement aid, not a structural approval. A high score means a supplier can support your designer’s calculation; the calculation itself is still a CIRIA C737 exercise at your cover depth, groundwater and traffic load. Storm Manage self-score updated July 2026.
