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.

Roof and wall sandwich panel thickness depends on insulation, fire rating and local climate, not price alone. First define indoor temperature, humidity, fire needs and wind or snow load, then select profile, core and thickness. Final sizes follow the agreed material schedule.

The steel frame is usually fabricated in the plant and erected on site. Foundations, concrete and embedments are typically done by a local civil contractor. We can issue base-plate sizes, anchor layouts and embedment notes. The contract scope defines the interface.

Fire protection depends on local code and the required fire rating. Some projects need only corrosion coating; others need intumescent paint or boards. Please state the fire rating and code in the inquiry. Site fire-coating work is not included unless confirmed in writing.

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.

Warranty period and coverage follow the contract and may differ by member and coating system. Shipping documents usually include a packing list and member marks, plus material or inspection papers named in the contract. No extra certificate is promised unless listed.

Export jobs can be loaded at the plant or warehouse. Members are packed by mark for site matching. Container type and quantity depend on span, member length and packing. Please state the destination port and whether inland haulage is required. Insurance and destination clearance follow the trade terms.

Color, profile and insulation core can be specified, subject to lead time and local availability. Please give a color code or sample. If a brand or core is required, include it in the inquiry so we can reply with lead time or an equivalent option.

Expansion is easier if bay spacing, gable conditions, crane or mezzanine loads are reserved in the first scheme. Please say whether a future extension, crane or mezzanine is planned. A building without reserves can still be modified, but foundations and existing members must be rechecked.

Export orders usually combine an advance and a balance against shipment, with the ratio, T/T or L/C set in the commercial terms. The Made-in-China profile lists common methods such as FOB, EXW, T/T and L/C. The signed contract controls; no single deposit ratio is fixed before agreement.

The range covers steel workshops, H-beam members, beams and columns, purlins and bracing, space frames and connection parts. Typical uses are industrial plants, warehouses and public buildings, in both custom pieces and volume lots.

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.

Please include project location and use, building size or span, drawings (PDF/DWG), steel grade and coating, quantity or area, target delivery and destination port. Fuller data speeds quotation and scheduling. If drawings are not ready, send size and loads first; we will list what else is needed.

Lead time depends on drawing freeze, tonnage, coating and the production slot. After drawings are locked, standard jobs ship in agreed batches. Rush orders can be reviewed, but they do not override confirmed contracts. The schedule is confirmed in writing with the quotation.

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.

Blasting and coating are done per job: typical shop primer, intermediate and finish coats, or hot-dip galvanizing when specified. Tell us the environment (indoor, coastal, chemical, etc.) and design life so film thickness or zinc coating can be set. Appearance and thickness are checked before dispatch.

Members are marked, bundled or framed in erection order, with a packing list for site matching. Inland haulage and booking can be arranged under common terms such as FOB, CFR or CIF. Port, sailing and insurance are set in the contract. Oversized pieces should be flagged early so transport can be planned.

Our core work is shop fabrication and delivery. We can supply erection drawings, piece marks and remote technical support. If you need a supervisor or erection assistance, state the programme and site conditions in the inquiry; we will assess it per project.

Most work is project-based and quoted by drawing and tonnage; there is no retail MOQ. Samples, repair pieces or small top-ups can be discussed, but price and lead time differ from volume jobs. Freezing main sizes early reduces stoppages and extra cost from drawing changes.

Steel intake, cutting, welding, coating and outgoing inspection can be traced as agreed. Mill certificates and dimensional/coating records can be issued with dispatch. If goods arrive damaged or off drawing, send photos and piece marks within the agreed period; we will assess replacement or repair. Warranty follows the contract.
