The main tee is manufactured from high-quality,continuously hot-dip galvanized steel strip through cold-forming processes,offering high strength and superior corrosion resistance.Its unique"C"or"U"shaped channel design provides excellent bending resistance,effectively preventing the ceiling from sagging or deforming under long-term load.The runner features a flat surface and precise dimensions,ensuring easy installation and a final,level ceiling finish.This product complies with strict building codes and is suitable for various commercial and industrial environments,making it the preferred choice for building a safe and reliable ceiling infrastructure.
The standard length is 3 meters(10 feet),with custom lengths available based on project requirements.Common thicknesses include 0.5mm,0.6mm,0.7mm,and 0.8mm to meet different load requirements.The flange width is typically 38mm,and the web height is commonly 50mm,60mm,or 70mm.Its rolled edges are specially reinforced to enhance rigidity.The product typically conforms to standards like ASTM C645(U.S.standard)or GB/T 11981(Chinese standard),ensuring the material's mechanical properties and zinc coating weight(e.g.,Z275)meet industry requirements.
Widely used in commercial building interiors such as office buildings,shopping malls,hospitals,and schools.As the primary runner,it is connected to hanger wires via ceiling clips.Cross tees are then vertically attached to its bottom using connecting clips,forming a stable load-bearing grid.Various finish panels like gypsum boards,mineral fiber tiles,and metal panels can be installed onto this grid.Its role is particularly critical in large spaces requiring support for heavy lighting fixtures or air ducts.
