A Singapore-headquartered manufacturer and supplier of Ring Lock scaffolding, tube & clamp and formwork — engineered, quality-controlled and delivered to the contractors building the world's most demanding energy and marine projects.
The ESTN brand began as ESTN Metal Engineering Pte Ltd in Singapore in 1996. Over three decades it has become an establishment of trust across the petrochemical, power, marine offshore & onshore, shipbuilding and civil construction industries. We hold the ESTN brand and the quality standard behind it: material is manufactured across our network of group and partner factories in China, engineered and inspected from our Singapore headquarters, and delivered worldwide through our own logistics.
On multi-year projects our material holds its strength and value — a lower total cost over the life of the job.
Every batch mill-certified, independently lab-verified, then checked by our own inspectors.
We design the system to your project and supply the full package — not just loose components.
Mission: to be one of the world's great construction suppliers and fabricators. Vision: the one-stop service for quality and reliable construction material supply. Values: Trustworthiness · Industrial Responsibility · Excellence · Customer Satisfaction.
