galvanize steel truss
High-Strength Structural Framing Solution for Modern Roofing Systems.
Galvanized Steel Trusses are engineered structural framing systems designed to support roofing sheets with superior strength, durability, and long-term stability. Manufactured from high-quality steel and protected with a zinc coating, these trusses offer a reliable alternative to timber, especially in environments prone to moisture, termites, and heavy structural loads.
They are widely used in residential, commercial, industrial, and institutional construction, providing consistent performance and reduced maintenance over the building’s lifespan.
Available Sizes and Thickness Options.
Galvanized steel trusses are manufactured in various profiles and gauges to suit different structural requirements, commonly ranging from:
0.70 mm – Light residential roofing
0.75 mm – Standard residential and commercial use
0.95 mm – Heavy-duty commercial and industrial structures
These options allow engineers to design truss systems that meet both load requirements and budget considerations.
Why Galvanized Steel Trusses Are Important.
1. Superior Corrosion Resistance
The zinc coating protects steel trusses from rust, making them suitable for humid, coastal, and high-rainfall environments.
2. High Structural Strength
Steel trusses offer consistent strength and dimensional accuracy, eliminating warping, shrinking, or cracking common with timber.
3. Termite and Fire Resistance
Unlike wood, galvanized steel trusses are:
Immune to termites and insects
Non-combustible, improving fire safety
4. Long-Term Durability
Properly galvanized steel trusses can last decades with minimal maintenance, reducing long-term structural costs.
5. Precision and Consistency
Factory-fabricated steel trusses provide uniform quality and accurate dimensions, ensuring easier installation and better load distribution.
Material Composition (Industry-Standard Galvanized Steel).
Galvanized steel trusses are produced from carbon steel coated with zinc, using industry-accepted galvanizing processes such as hot-dip galvanization.
Typical material composition includes:
1. Steel Core – ≈ 98–99%
High-strength carbon steel forms the structural backbone.
Provides excellent load-bearing capacity, rigidity, and dimensional stability.
Designed to withstand wind loads, roof weight, and structural stresses.
2. Zinc Coating – ≈ 1–2%
Applied uniformly to protect the steel from corrosion.
Zinc acts as a sacrificial layer, preventing rust even if the surface is scratched or cut.
Common coating standards include Z275 or equivalent, depending on application.
