    Structural C, Z and H purlins for industrial and commercial buildings

    We provide a wide selection of C, Z, H, and other purlin profiles that serve as essential structural members in steel construction. Coating levels can be customized from 80 g/m² to 450 g/m² of galvanization, depending on design requirements, and material strength can be adjusted to meet different regional certification standards. With highly automated production lines, the purlins are manufactured with precise punching so that bolt holes align exactly with the needs of each project. This ensures reliable performance, faster assembly, and long service life.

    Features
    • Available in a wide range of profiles, including C, Z, and H types, so they can be matched to different structural designs.
    • Material strength and galvanization levels can be customized to meet both project specifications and international standards.
    • Each purlin is manufactured with automatic equipment that guarantees accurate punching and consistent dimensions.
    • The purlins have a light design, are easy to move and install, yet they are strong enough to keep buildings stable.
    • A galvanized coating protects the steel against rust and weathering, so the purlins keep their performance and appearance for many years, even in tough environments.

    Purlins are commonly used in large steel buildings because they transfer the weight of the roof and walls to the main structure; this helps keep everything stable even in wide-span designs. The purlins we offer are available in profiles like C, Z, or H; their steel grade and galvanization level can be adjusted according to clients' requirements. Since we produce them with automated equipment, the punching is accurate and the quality stays consistent, which makes installation easier and more reliable.

    Yes. Purlins can be made in different sizes, thicknesses, and spacing to match the load requirements that different projects have. Thanks to this flexibility, they work just as well for smaller warehouses as they do for large industrial buildings or public facilities.

    The zinc coating provides strong resistance to corrosion, extending the service life even in harsh environments such as coastal or areas where there's high-humidity. Depending on the coating weight, they can meet both standard and demanding durability requirements.

    Purlins are an important part of steel structures and are commonly found in factories, warehouses, logistics hubs, airports, shopping centers, and exhibition halls. They support the roof and wall cladding while keeping the whole structure stable and secure.
