Completed Steel Structure Projects at Home and Abroad

The cases below show steel buildings we have delivered for workshops, production halls, storage and special structures. Projects are organized by building type and area, so buyers can compare frame layout, span choices and finish level with their own requirements.

Most deliveries use portal frames built with Q235B or Q355B members, with wall and roof cladding selected around climate, insulation and fire protection needs. Indoor crane provisions, mezzanine floors and large door openings are marked in the drawings before production, which keeps the frame matched to the equipment or storage plan inside. Our steel building range covers the main frame types these projects use; industrial workshops and storage buildings make up the majority of overseas orders.

Each record lists the building area, structure form and main application, while detailed drawings and photos for a specific project can be requested through the contact page. For design questions before a project starts, the technical services team reviews layout and member choices against the site plan you provide.
