Characteristics<\/strong><\/p>\n

The thin-walled Z section is a product of cold forming. Its use provides significant benefits in both construction cost and time, while also improving quality. This is because the strength-to-weight ratio is better than that of conventional purlins, transportation costs are lower due to its lighter weight, there is no material waste since cutting and perforation are performed to the required dimensions, and additionally, during installation no welding is required, as the elements are assembled using bolts.<\/p>\n

Applications<\/strong><\/p>\n

The Z thin-walled section is used in building construction as a purlin for supporting roof covering materials.<\/p>\n
