Light gauge steel frames, engineered to last
Phu Nguyen Steel designs and roll-forms G550 steel wall frames, trusses, floor joists and structural steel for homes, resorts and commercial buildings, made in Vietnam to international quality standards.
A Vietnamese manufacturer building for the global market
Founded in 2004, Phu Nguyen Building Materials & Machinery JSC operates a 20,000 m² factory at Chau Son Industrial Park, Ha Nam.
Our production lines are equipped with advanced, highly automated machinery that delivers consistent precision on every member. The result is a framing system that meets the diverse requirements of builders, developers and homeowners, backed by a 10-year warranty on structural integrity.
- Engineered in-house with 3D modelling and structural design
- Automated roll-forming for millimetre-accurate studs, joists and trusses
- Zinc-aluminium-magnesium coated G550 steel for long-term corrosion resistance
Steel framing solutions for every build
Four core product lines that work together as one integrated structural system.

Learn moreWhy light gauge steel outperforms timber
Steel frames are fast becoming the preferred choice for homes and commercial buildings, and for good reason.
100% termite-proof
Unlike timber, steel frames can never be eaten by termites or borers. No chemical treatments and no ongoing pest maintenance.
Non-combustible
Steel will not burn, char or feed the spread of fire, which can make the difference between repairing a building and rebuilding it.
Straight for life
Engineered steel will not rot, warp, twist, shrink or settle. Walls stay true, so plaster cracks and sticking doors become a thing of the past.
Faster to build
Pre-fabricated, labelled and pre-punched for services, our frames go up quickly with less labour and far less on-site waste.
High strength-to-weight
G550 steel is one of the strongest framing materials for its weight, enabling longer spans and lighter foundations.
Fully recyclable
Steel is endlessly recyclable and its long lifespan reduces replacements and repairs, supporting more sustainable construction.
From drawing to standing frame
One team handles engineering, manufacturing and delivery, so every stud, joist and truss arrives ready to fit.

Share your architectural drawings or concept. We review scope, loads, budget and timeline, then send a clear quotation.
Design & engineering
Our engineers model the entire frame in 3D, check it structurally and produce shop details for every member.
Precision manufacturing
Automated roll-formers turn G550 coil into labelled, pre-punched members, assembled into panels and trusses under ISO 9001:2015.
Delivery & installation
Frames are packed by assembly sequence and delivered to site. Screw-fixed connections mean fast, clean installation with no welding.
