Hot Dip Galvanized
25-60 days
✔ Superior Strength-to-Weight Ratio
Made from high-grade steel (Q235B/Q355B, ASTM A36)
Supports heavy loads with minimal deflection
Ideal for long-span applications (up to 20m+)
✔ Fast & Easy Installation
Pre-engineered for quick bolt-on assembly
Reduces construction time vs. traditional beams
Compatible with open-web designs for HVAC/electrical integration
✔ Cost-Effective Design
Uses 30-50% less steel than solid beams
Lower foundation requirements due to lightweight nature
Pre-punched holes simplify MEP (mechanical/electrical/plumbing) routing
✔ Customizable Configurations
K-Series (standard) – For typical floor/roof loads
LH-Series (long-span) – Up to 20m spans
DLH-Series (deep long-span) – Heavy industrial use
Gable ends – For sloped roof systems
✔ Durable & Low-Maintenance
Hot-dip galvanized or painted finishes available
Resists corrosion, fire (with intumescent coatings), and pests
50+ year lifespan with proper maintenance
