What to ask for on a bill of materials
- Exact materials and ratings (PN/Class, seat material, SDR) — not only a product photo.
- Fusion or mechanical method allowed for HDPE joints, plus any datalogging requirements.
- Testing and commissioning responsibilities — who witnesses, who signs.
- Substitution rules — written approval paths before you swap brands.
How we talk about compliance
We supply products rated for the applications described on manufacturer datasheets and commonly specified for South African water and civils work when those datasheets align with your tender pack. We do not fabricate certificate numbers or claim approvals we cannot evidence on paper.

Specification FAQs
Will you stamp my drawing as compliant?
No. Compliance is a chain: engineer of record, installer QA, and manufacturer instructions. We supply products with datasheets; we do not sign drawings.
How should I reference South African standards on a BOM?
List the exact standard number, edition, and clause your engineer expects — then list the product datasheet that evidences conformance for that clause. If you are unsure, ask the engineer to issue a clarification before you buy.
Can you help interpret SANS 4427 or related piping standards?
We can point to common tender language and manufacturer documentation, but we do not provide engineering interpretation of national standards.
What should I ask for on HDPE pressure jobs?
SDR/PN class, fusion method allowed, testing regime, and whether substitutions require written approval. Pair those questions with our high-pressure line page and your WPS.
Where do downloads fit?
Our downloads hub carries indexable summaries of each list — useful when PDFs are paused. It explains revision workflow without exposing unstable pricing.
