Сборный стальной каркас, здание складского ангара из стальных конструкций Q235 Q355B

To generate an accurate engineering quotation, please provide: (1) building dimensions — length, width, and eave height; (2) intended use (warehouse, workshop, processing plant, etc.); (3) country and city of construction; (4) local maximum wind speed and snow load data; (5) seismic zone level if applicable; (6) whether an overhead crane system is required and at what capacity; and (7) your preferred enclosure system (insulated panels or single steel sheet). Preliminary drawings are helpful but not required at the inquiry stage.

Q235 is a standard-grade carbon structural steel suitable for conventional industrial workshops and warehouses with moderate load requirements and no crane systems. Q355B is a higher-yield structural steel with greater tensile strength, recommended for crane-integrated workshops, buildings in high-wind or seismic zones, and facilities carrying heavy roof or floor live loads. KXD’s structural engineering team will specify the appropriate grade — or a combination of grades for different structural members — based on your building’s load parameters after reviewing your project requirements.

Yes. Third-party inspection by SGS, BV, or ITS is available at any stage of production — covering raw material verification, welding quality (including ultrasonic testing), dimensional checks, surface treatment, and pre-shipment final inspection. Inspection scope and timing are coordinated with the buyer’s requirements. All inspection reports and quality documentation are provided as part of the shipment package.

Yes. KXD’s engineering team is experienced with structural design and detailing to ASTM, AISI, DIN, and BS standards in addition to the Chinese GB standard. CE EN1090 certification covers the fabrication process. For projects in specific regulated markets — such as the EU, Australia, or the USA — buyers should confirm the applicable design code at the inquiry stage so that engineering calculations and connection details are produced to the correct standard.

Standard fabrication lead time is approximately 30–45 days from drawing confirmation, depending on order volume and complexity. For large-scale projects — such as multi-building industrial parks or phased campus developments — partial shipment is available, allowing earlier site work to begin while remaining components are being fabricated. Delivery timeline is confirmed in the sales contract based on the specific order scope.
