What does Ke Ming Steel Structure manufacture?

We are a prefabricated steel building manufacturer and global turnkey supplier. We design, fabricate, and export a full range of steel structures: industrial workshops and plants, steel structure warehouses, multi-storey steel frame buildings, livestock and poultry steel barns, cold storage / cold-chain facilities, prefabricated steel bridges (truss & girder), and steel truss floor slabs.

What certifications and standards do your products meet?

We hold National Grade 1 construction qualifications and a National Class I steel manufacturing license. Our management systems are certified to ISO 9001, ISO 14001, and ISO 45001. Products carry CE marking for the EU, Australian AS/NZS certification, North American ASTM compliance, and Southeast Asian SNI and PNS approvals. We also manufacture to AISC standards with full material traceability, weld audits, and third-party inspection. We hold 15 independent technical patents.

What is your production capacity and factory scale?

We operate a 120,000 m² smart industrial park with a total investment of RMB 230 million. Equipped with fully automated CNC processing lines, our annual output reaches 100,000 tons of prefabricated steel components and 1 million m² of steel truss floor slabs. We maintain self-built R&D laboratories and a professional welding research institute.

Do you provide structural design and shop drawings?

Yes. We provide integrated design services using PKPM and TEKLA, including structural calculation, fabrication (shop) drawings, and 3D models. Drawings and 3D assembly guides are delivered in international and localized formats to support accurate on-site erection.

Can you customize structures to local building codes and loads?

Absolutely. Every project is engineered to your local code requirements, including wind speed, snow load, seismic zone, and live/dead load specifications. Share your site conditions and we will design accordingly.

What is your typical lead / delivery time?

From design approval to sea loading, we deliver a complete structural package in approximately 15 days, enabled by PKPM/TEKLA-driven modular fabrication. Exact timing depends on project size and customization.

Do you provide on-site installation and overseas support?

Yes. As a turnkey supplier we provide overseas on-site installation supervision, 3D assembly guides, localized erection manuals, and remote or on-site technical support to ensure correct assembly.

What surface treatment and anti-corrosion options do you offer?

We offer galvanizing, painting, duplex systems, and powder coating, with marine-grade anti-corrosion coatings for export shipments. The optimal coating is recommended based on the project environment (humidity, salinity, industrial exposure).

Which countries do you export to, and do you handle logistics?

We have delivered projects to 20+ countries across Asia, the Middle East, Africa, Europe, Australia, and the Americas. We manage export packaging, container loading, and global logistics coordination, with secure marine packaging that protects components in transit.

What materials and steel grades do you use?

We use certified structural steel from China's leading mills with full material traceability. Grades and specifications are selected per project and code; the exact grade (for example Q235B / Q355B or equivalent ASTM / EN grades) is specified in the proposal.

How do you ensure quality control?

All components undergo ISO-controlled production with ultrasonic testing, weld audits, and third-party certification before delivery. Material traceability and load performance are verified at each stage of fabrication.

What is your minimum order quantity (MOQ)?

MOQ depends on product type and project scope. We serve both single-building buyers and large-scale developers. Send us your building size and we will confirm the MOQ and pricing.

How does your pricing work — is it factory-direct?

Yes, we ship factory-direct worldwide, eliminating middleman markups. Pricing is quoted per ton or per project based on design, materials, coating, and logistics. China's steel supply chain and our automated production allow competitive per-ton pricing.

What information do you need to provide a quote?

To prepare an accurate quote, please share: building type and dimensions (length × width × eave height), intended use and local loads (wind / snow / seismic), preferred cladding and insulation, coating requirement, destination port, and target delivery date.

What is the typical project workflow?

1) Inquiry & requirements → 2) Free consultation & quotation → 3) Design & shop drawings → 4) Contract & production (≈15 days) → 5) QC & packaging → 6) Shipping → 7) On-site guidance / installation → 8) Lifetime after-sales support.

Do you offer warranty and after-sales service?

Yes. We provide lifetime expert service and after-sales support, including technical guidance, spare-parts advice, and re-order support. Structural warranty terms are defined per contract.

What is the service life of your steel structures?

With proper design, coating, and maintenance, our steel structures typically deliver a service life of 30–50 years, depending on the environment and maintenance regime.

Which international design codes do you design to?

We design to the code required by your project — commonly AISC 360 (United States), EN 1993 / EN 1090 (European Union), AS 4100 (Australia / New Zealand), GB 50017 (China base), and the applicable local national standard. Our engineering team confirms the governing code and load combinations at the quotation stage.

What connection methods do you use — bolted or welded?

We use a hybrid approach optimized per element. Field connections are predominantly high-strength bolted (ASTM A325 / A490 or equivalent) for fast, accurate erection, while shop fabrication uses automated welding to AWS D1.1 / EN ISO 3834 standards. Bolt grades and classes are specified in the design.

What clear-span and height capabilities can you achieve?

Our prefabricated frames regularly achieve clear spans of 30–60 m without intermediate columns for warehouses and workshops, with eave heights up to 12–15 m and higher for specialized plants. Multi-storey frames and bridges are engineered to project-specific geometry. Exact limits are confirmed during design.

How do you handle seismic and wind load design?

Lateral loads are resisted by braced frames, moment frames, or portal systems selected for the seismic zone and wind speed at the site. We run full load combinations — dead, live, wind, seismic, snow, and crane — per the governing code and verify drift and overall stability before drawings are released.

What cladding and insulation systems do you supply?

We supply single-skin cladding and insulated sandwich panels (PU, PIR, rock wool, EPS) for roofs and walls, with U-values matched to the building's thermal requirement. Cold storage buildings use enhanced insulation and vapor barriers; acoustic and fire-rated non-combustible rock wool options are available.

What fire-protection options are available for steel members?

Steel can be protected with intumescent paint, cementitious spray, or board encasement to achieve the required fire-resistance rating, typically 1–3 hours, per the local fire code. Fire-rated cladding and compartmentation are also integrated where specified.

What are your galvanizing and paint coating standards?

Hot-dip galvanizing follows ASTM A123 / ISO 1461. Liquid paint and duplex systems are specified per ISO 12944 (C2–C5 environments), with dry-film thickness verified by gauge. Marine-grade coating systems are applied for export and coastal projects.

Do you provide crane-ready industrial workshops?

Yes. We design workshops for overhead bridge cranes, including crane beams, column reinforcement, rail foundations, and runway alignment, rated to the required tonnage and class of service.

What foundation and anchor-bolt information do you provide?

We supply anchor-bolt layouts, embedment drawings, and foundation reaction loads — vertical, horizontal, and moment — for your local foundation engineer to design footings and piles. We coordinate bolt tolerance and sleeve details with the erection team.

What erection support and on-site supervision do you provide?

We provide 3D assembly models, erection sequence drawings, bolt lists, and on-site supervision or remote guidance. A typical crew with a mobile crane can erect our pre-bolted frames efficiently; we advise on crane capacity and lifting plans.

How are components packed and loaded for shipping?

Parts are marked, bundled, and packed in secure marine packaging with corrosion protection, then loaded by our logistics team to maximize container utilization. A detailed packing list and marking plan accompany each shipment for easy on-site sorting.
