Listing ID #4437449

Sandco Metal Industries specialize in manufacturing of Square Steel Pipes available in various grades and dimensions at affordable cost with no quality compromise. We are manufacturing Square Steel Pipes from past 25 years under supervision of technical experts with their expert guidance and support. Our Organization is ISO-9001:2008 certified with added advantage of products electro polishing, cutting as per customer requirements.
Mild steel Pipes contains 0.05–0.25% carbon making it malleable and ductile. It has a relatively low tensile strength and small percentage of carbon also known as low-carbon steel making it strong and tough. It is often used when large quantities of steel are needed, for example as structural steel. The density of mild steel is approximately 7.85 g/cm3 (7850 kg/m3 and the Young's modulus is 200 GPa (29,000,000 psi). Our Mild Steel Pipes are available as seamless, welded and ERW (ERW stands for Electric Resistance Welded) pipes .
Square Steel Pipes also known as “Square Hollow Sections (SHS)” are cold formed and welded from either hot rolled, cold rolled, pre-galvanized or stainless steel. In order to form the square steel section the mother tube, a round steel tube, has to be formed first. From a round tube rolls are used that progressively press the round tube into a square hollow section. They are used for structural purposes, special piping systems , architectural work, and many other general purpose fabrication works. Square Steel Pipes can be supplied with black paint mill finish or with anti rust oil coating for surface protection of the pipes and are offered in both mechanical and structural grades.
Seamless Square Steel Pipes
Seamless Square Steel Pipes Supplier, Seamless Square Steel Pipes Exporter, Seamless Square Black Pipes, Seamless Square Shape Pipes
Seamless Square Steel Pipes are manufactured by using an extruded hollow tube or a drilled solid bar which then undergo various tube reduction processes to meet customers specifications.
Welded Square Steel Pipes
Welded Square Steel Pipes Supplier, Welded Square Steel Pipes Exporter, Welded Square Black Pipes, Welded Square Shape Pipes, Welded Square Pipe Manufacturer in India
Welded Square Steel Pipes manufacturing process starts with cold rolled strip of metal, roll formed into tubular shape and seam welded without the use of any filler material which then undergo various cold working techniques like Pilgering, cold drawing etc., until it reaches the exact size, tolerances, and temper in accordance to customer’s specifications.
ERW Square Steel Pipes
ERW Square Steel Pipes Supplier, ERW Square Steel Pipes Exporter, ERW Square Black Pipes, ERW Square Shape Pipes, ERW Square Pipe Manufacturer in India
ERW Square Steel Pipes manufacturing process involves spot and seam welding where the sides are trimmed to control the width and the condition the edges for welding. It is then passed through a number of contoured rollers which cold form the stainless steel into a tube. ERW stands for Electric Resistance Welding.
