Independent and in-house testing since 1998, an ISO 9001-based quality system since 2000, and verification by the industry's most recognised certifiers.
We break quality assurance into the three points where it can be won or lost — source, production and workmanship.
All steel used in production is screened and arrives with mill certificates. We don't stop there: an independent, respected laboratory verifies that every batch meets or exceeds the appropriate BS / EN / JIS / ASTM / ANSI / GB specification — as required by the client.
Our welding process was authored by an independent professional engineer. Manufacturing follows a stringent, safety-first process with quality-control records kept to ISO 9001 — because construction safety depends on scaffolding quality.
We take a conscientious, responsible approach to good business — employing quality people, running our own test labs and providing on-site erection training. A dedicated engineering and inspection team keeps quality in our hands.
Our products and systems are approved and tested by internationally recognised certification bodies.
The Ring Lock scaffold system is approved under PSB Singapore test certificates. Tubes, clamps, ladder beams, jack bases and props are approved under SGS, TÜV and Lloyd's test certificates. Our manufacturing holds ISO 9001 certification.

Full inspection standards and load-test reports for tubes, clamps, metal planks and screw jacks are available on request.
ESTN supplies against the international standards specified on global project tenders — so a single supplier can meet the requirements of contractors working to different codes.
Steel is verified against mill certificates and independent laboratory testing before it enters production.
Tell us the specification — we'll confirm the standards and certificates that apply.
