C - purlin section
Z - purlin section
Geometric Steels manufacture a complete range of ‘C’, ‘Z’, ‘U’, ‘L’ Purlin and Hat section. Purlin and Girts for a wide range of applications up to 3 mm thickness. Made from quality high tensile GI, CR & HR Steel. Geometric Steels Purlin and Girts can be supply plain or punched. This is a fully integrated system allowing for flexible design options. Geometric Steels purlin is manufacture from high tensile steel for increased strength, reduced weight, and long service life.
Purlins and girts are complementary products used in walls and roofs of Structural steel buildings. All purlins and girts are cold-formed using high-performance steel to maximize capacity overweight while meeting the strictest quality standards.
Steel used to fabricate purlins and girts comply with the requirements of 245Mpa and 350Mpa.
Cold-formed C and Z section purlin can be manufactured as per customer structural requirement from web height 80mm to 300mm, Flange 40mm to 80mm, and Lip 10mm to 20mm in thickness of 1.00mm to 3.00mm.
COMPLETE FABRICATION SERVICES
In addition to standard cut-to-length, punching, and painting services, geometric steel offers clients a complete fabrication solution for purlins and girts. Clients who rely on geometric steel for the fabrication of purlins and girts, profit from multiple benefits:
• A finished product delivered directly to site; • Time saving (no product handling); • Lower labor costs.
Geometric Steel offers a range of purlins and girts from 80mm to 300mm in Z and C profiles web height, cut to length, un-punched, or punched. All purlins and girts are manufactures from high tensile, galvanized steel of 245Mpa and 350Mpa, with a minimum Z90 to Z 275GSM Zinc coating.
Purlins can be used as a structural steel in lightweight buildings but must be used in accordance with a design certified by an engineer. Selection of the correct coating weight is critical when specifying purlins. Z80 to Z275 gsm Zinc coating is suited to many applications as long as it is not a highly corrosive environment. For high corrosive environments specify Z450 and consider other corrosion protection measures, such as powder coating.
If not required for immediate use, the Z or C sections or bundles should be neatly stacked clear of the ground. For extended outdoor storage duration, the sections should be store with a small incline so that no water can pool.
Sections/bundles and accessories should not be left exposed in the open for extended periods of time. If unavoidable then protect the sections/bundles from moisture and rain with waterproof covers.
SAFETY WORK PRACTICE
Geometric Steel Purlins and Girts are not designed for walking on. Residual Oil from the Manufacturing process May be present and slipping can occur. Appropriate lifting equipment and work platform must be used
- Never walk on purlin during installation, use appropriate equipment
- Always use approved safety harnesses or other suitable safety equipment during installation
- Never walk on bridging
- Ensure safety mesh is in place
GEOMETRIC STEELS C and Z purlin sections are normally supplied with hole punch of 28 x 14 or 28 x 18 as per customer requirement. Holes are required at cleat support, laps bridging point, sag rod fixing, or as specified on detail sheets supplied prior to manufacturing.
Welding of purlins, girts, and bridging is not recommended. Welding any cold rolled, high tensile material affects the material properties and removes the galvanized coating. This can cause reduced life of a member.
