Space Grid Roof Solution for Irregular Halls

Space Grid Roof Solution for Irregular Halls

When a portal frame is not enough, a grid or truss is planned by plan, hanging loads and supports.

Halls, exhibitions or irregular roofs more often use grids or tubular trusses. Portal frames suit rectangular plants; shop and erection also differ. Read the plan and hanging loads first.

Send plan, supports, hanging and the roof build-up. Area without a plan is only a concept. Uncalculated grid and member sizes are omitted.

Units are often assembled then placed. Coating follows building type and exposure.

Attach architectural plan and section.

FAQ

  • Can you fabricate from our drawings?

    Yes. Send structural, shop or detailing drawings and we will cut, weld, drill and coat to those drawings. Member sizes, connections and joints can be adjusted per project. If you only have an architectural layout, we can discuss loads, span and use, then propose a steel scheme.

  • Which steel grades and codes do you follow?

    Common carbon grades can be specified (for example Q235, Q355 or an agreed equivalent). Welding, holes, geometry and coating follow the contract drawings and the destination code. For export, state the required standard in the inquiry (GB, EN, ASTM, etc.) so material and inspection can match.

  • Which design software and drawing formats do you accept?

    Design and detailing follow the drawing set agreed for each project. Please send plans, elevations, sections, plus load, span, bay spacing and cladding requirements. PDF or common CAD formats are acceptable. A sketch or dimension list is enough for a first scheme before shop drawings.

  • How are wind and snow loads decided?

    Wind and snow loads follow the project location, the local code and the owner design brief. There is no single default number. Please provide site, basic wind pressure, snow load, seismic data and roof live load. A first estimate can use the stated building use; fabrication follows approved drawings only.
