PRODUCT DESCRIPTION

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.

PRODUCT DESCRIPTION

Square tube is formed from coil and then ran through a series of dies.lt's welded from the inside to form its shape. Square tubes are generally used for maintenance and structural purposes.

Some examples of square tubing applications would be building construction, railings, and sign posts. They are measured by their outside dimensions and their wall thickness.

square Tube is available in the following metal types:Alloy Steel

Mild Steel Carbon Steel stainless Steel

Square tube has similar uses to RHS and is used for both industrial and construction applications. Square section RHS is available in the same thicknesses as RHS and dimensions range from 20 mm x 20 mm to 400 mm x 400 mm.
