Core Design Features Differentiate Bewteen Heavy and Ordinary Steel Buildings
1. Thickened main beam & column H-beam web and flange thickness increased greatly, built-up welded box column widely used, enhance vertical bearing capacity and anti-sway performance under long-term dynamic vibration.
2. Independent heavy crane beam system Separate crane girders installed on corbels of main columns, not shared roof rafter load. Special anti-fatigue welding process to avoid crack under thousands of daily crane lifting cycles.
3. Reinforced rigid node connection Full penetration groove welding + high-strength 10.9 bolt composite connection, resist repeated dynamic impact load, prevent loose connection after long service.
4. Vibration isolation design Add vibration damping support under equipment foundation and crane beam, reduce resonance damage to steel frame from stamping, forging, rolling mill machines.
5. High temperature anti-corrosion & heat resistance coating Metallurgy, casting, chemical workshops adopt heat-resistant paint system; coastal heavy industry projects use full hot-dip galvanizing + top anti-corrosion finish.
