Fabrication & Manufacturing

From the largest built-up members to small fittings, every component is cut, welded, blasted, painted and coded in our own plant under certified quality systems.

Our fabrication plant at Hai Son Industrial Park, Tay Ninh, produces components from the largest to the smallest and from simple to complex – including oversize and special structures – with a capacity of around 40,000 tonnes per year.

Fabrication follows certified quality and welding management systems recognised in our export markets: AS/NZS 5131 CC3 for Australia and New Zealand, EN 1090-2 EXC3 for Europe, ISO 3834-2 for welding quality, IAS AC472 for the US market and BC1 for Singapore. Quality is inspected from incoming material, through each production step, to the finished product.
