Lightweight Steel Tubes
High-quality lightweight steel tubes for structural, fabrication, and construction applications, manufactured to PNS 2145:2020 standards.
Designed for strength, versatility, and cost efficiency, lightweight steel tubes are ideal for frameworks, fencing, steel fabrication, and general construction projects across the Philippines.
Overview
Lightweight steel tubes are designed for applications that require practical support, easier handling, and efficient installation. Their reduced weight makes them suitable for construction and fabrication work where flexibility, workability, and cost efficiency are important.
These tubes are ERW-manufactured and available in:
- Black Iron (BI)
- Galvanized Iron (GI)
With a balance of strength and ease of use, lightweight steel tubes are commonly used for fencing, railings, scaffolding, frames, and other non-water structural applications.
