When you are planning an industrial shed, factory building, or a pre-engineered structure in Bangalore, two components quietly hold the entire roofing system together – C purlins and Z purlins<\/strong>. These cold-rolled steel sections are the secondary structural members that carry your roof panels, wall cladding, and insulation loads. Without the right purlin – right thickness, right galvanization, right dimensions – even premium roofing panels will fail early.<\/p>\n<\/div>\n

Metro Puf Industries, based in Doddaballapur, Bangalore, manufactures precision C and Z purlins alongside our full range of PUF sandwich panels and roofing sheets, giving you single-source supply for your entire building envelope.<\/div>\n

What Are C Purlins and Z Purlins?<\/h3>\n
\n

C purlins and Z purlins are cold-formed, lightweight steel structural sections used as horizontal secondary framing members in industrial and commercial buildings. They are fixed between main structural frames and directly support roof sheets, wall panels, and insulated sandwich panels.<\/p>\n<\/div>\n

\n

C Purlins<\/strong> – shaped like the letter “C” – are the standard choice for simple span applications like single-bay sheds, smaller warehouses, partition walls, and wall girts.<\/p>\n<\/div>\n

Z Purlins<\/strong> – shaped like the letter “Z” – are engineered for continuous span applications. Because Z purlins can be overlapped at support points, they deliver higher structural efficiency over long spans. This makes them the go-to choice for large industrial buildings, logistics warehouses, and PEB structures.<\/div>\n
Both types are cold-rolled from high-tensile galvanized steel coil, conforming to IS 10748<\/strong> for material grade and IS 801\/811<\/strong> for design.<\/div>\n
