RUNYING Steel Group is a leading global manufacturer of high-strength cold-formed C-purlins, Z-purlins, and U-channels. Precision roll-formed from premium hot-dip galvanized (Z60–Z275) or Galvalume (AZ100–AZ200) steel, our steel purlins deliver an optimal section modulus while providing up to 25% weight savings compared to conventional angle steel. Available in Q235B, Q355B, S350GD+Z, and G550 high-yield grades, our purlin systems are designed for rapid bolt-on installation in steel structures, roof/wall girts, and PV solar mounting frameworks.

Key Performance Advantages

1. High Strength-to-Weight Ratio:

 · Delivers 30% longer span capability compared to standard hot-rolled channels while reducing total structural dead load by 25%.

2. Pre-Engineered Hole Punching:

 · Customized inline punching (300mm/600mm pitch spacing) for fast bolt connections with cleats, sag rods, and diagonal bracing.

3. 1500+ Hours Corrosion Protection:

 · Galvalume base and high-zinc coatings withstand harsh coastal (C4/C5), chemical, and agricultural environments with up to 25 years of service life.

Seaworthy Export Packaging & Container Loading

To maximize container space and protect profiles from deformation during sea freight:

 · Steel purlins are tightly strapped into 2 to 3-ton hex bundles with steel protectors.

 · Optimized container loading schemes allow up to 18–26 Metric Tons per 40HQ container.

 · Fast shipments dispatched directly from Tianjin Port, China.
