HFI WELDING PIPE/SCAFFOLDING PIPES
Scaffolding Pipes are widely used for supporting man and materials, tools and tackles during construction, alteration, |
demolition and maintenance works because of their several advantages over conventional type of timber /bamboo |
scaffolding. |
Generally, made of hot dipped, galvanized steel, which offers long-term corrosion resistance, it won't rot, absorb |
moisture, split, splinter, swell, warp or burn, thereby providing considerable life-cycle cost savings. While weighing |
less than the average wood scaffold plank, steel scaffolding is stiffer over any given span,reducing bounce and providing |
a more stable platform. |
Steel Scaffold Tubes, black, 48.3 mm O.D., mild steel,steel tubes conform to GB/T13793-2008,BS1139-82,EN39, |
JIS G3444.These are made available in random lengths of 3M to 6M or of required cut length painted in desired color. |
