Solar Panel System

Solar panel systems include steel or aluminum support structures used to install photovoltaic panels on steel building roofs, industrial facilities, farms, carports, and ground-mounted solar projects. Welldone Steel can provide customized solar mounting structures according to roof type, panel layout, wind load, installation angle, and project capacity.

Doors & Windows

Doors and windows are essential accessories for steel buildings, affecting access, ventilation, daylighting, safety, and daily operation efficiency. Welldone Steel supplies roller shutter doors, sliding doors, steel personnel doors, fire-rated doors, aluminum windows, PVC windows, ventilation windows, and related accessories for industrial, commercial, agricultural, and storage buildings.

Steel Decking

Steel decking is a profiled galvanized steel sheet used as permanent formwork and reinforcement support for concrete floors in steel structure buildings. It is commonly used for mezzanine floors, multi-story steel buildings, equipment platforms, warehouses with office areas, and industrial floor systems.

Steel Sheets

Steel sheets are widely used for roofing, wall cladding, partitions, trims, and building envelope systems in steel structure projects. Welldone Steel supplies color-coated, galvanized, aluminum-zinc, and corrugated steel sheets for warehouses, factories, sheds, agricultural buildings, and commercial facilities.

Sandwich Panels

Sandwich panels are insulated building envelope materials used for steel structure roofs, walls, cold storage rooms, clean workshops, prefab buildings, and agricultural facilities. They combine two metal surface sheets with an insulation core to improve thermal performance, installation speed, and building appearance.

Purlin C/Z

C/Z purlins are cold-formed secondary steel members used to support roof sheets and wall cladding. They are lightweight, economical, and essential in pre-engineered steel buildings.
