OEM ODM Customized Steel Structure Workshop with Galvanized Sheet and Anti-Rust Painting

We’ve built these for years, but the truth is, a steel structure workshop isn’t something you order on a whim—the lead time can stretch to 20 days or so if you want hot-dip galvanized instead of standerd anti-rust painting, and that’s just the start. It basically works best for warehouses or industrial buildings where you don’t need a super tight schedule, because the main H beam frame, in Q235B or Q345B steel, handles the load fine—most buyers go with the 10-meter length for a typical bay.

The length runs from 4000 to 15000mm, with web plate thickness between 6 and 32mm, and wing plates from 6 to 40mm—we usually have stock in the mid-range sizes, but confirm lead time for the thicker ones. Height can go from 200 to 1200mm, which is pretty much standard for a workshop, though it’s not great for high-rise appliction where you need tighter tolerances than this offered.

Surfce treatment is either two coats of anti-rust paint or hot-dip galvanized—the galvanized holds up better in wet climates, but the painted finish is easier to touch up on-site. The purlin type is C or Z, ranging from C120 to C320 or Z100 to Z200, and you’ll get X-type bracing with plain or high-strength bolts; it’s all welded connection, so no loose parts to worry about.

Accessories like skylight belts, ventilators, down pipes, and gutters are included in the package—we’ve found that most buyers forget to ask about the gutter sizing until the last minute. The roof and wall use 0.5mm or 0.6mm galvanized sheet with sandwich panel or color plate, and the color is customizable, though we don’t offer every Pantone shade.

One thing we don’t do is provide the foundation design—that’s on your engineer, as the frame structure itself just bolts together. The model number is ML265, and the standard is GB, so it’s fine for most industrial builds, but we’ve had a few buyers ask for a CE mark and that’s not available on this line.
