Overview of ZOKECRANE Structural Steel Frames
Engineered and manufactured by Henan Zoke Crane Co., Ltd., ZOKECRANE structural steel framing systems utilize high-strength structural steel grades (such as Q355B, Q355D, Q235B, and ASTM A36 / A572). Built in strict accordance with ISO, CE, AISC, and EN standards, our steel structure frames incorporate primary framing components (H-beams, box columns, crane runway beams), secondary framing (purlins, girts, tie rods), and complete structural hardware, providing turn-key industrial building solutions for overseas clients.

Core Product Advantages & Engineering Features
- High Load Capacity & Crane Optimization: Specifically custom-engineered to absorb dynamic impact forces, brake thrusts, and heavy wheel loads generated by high-capacity overhead traveling cranes.
- Precision Prefabrication & Rapid Field Assembly: All steel columns, rafters, and crane runway beams are CNC-cut, drilled, and welded in our factory, enabling 100% bolted field erection with zero on-site cutting or welding.
- Superior Seismic & Wind Resistance: Flexible steel structure frames deliver exceptional earthquake resistance, high ductility, and wind load resistance capable of withstanding typhoon conditions.
- Advanced Surface Anti-Corrosion Protection: Automatic shot blasting up to Sa 2.5 cleanliness followed by multi-coat epoxy systems or hot-dip galvanizing ensures a service life exceeding 50 years in corrosive environments.
Industrial Applications of Structural Steel Frames
ZOKECRANE heavy steel structure frames provide structural foundations across various heavy industrial and commercial sectors worldwide:
1. Heavy Machinery & Steel Manufacturing Workshops
Large-span industrial workshops outfitted with heavy crane runway beams for manufacturing overhead cranes, transformers, and industrial equipment.
2. Logistics Warehouses & Storage Terminals
Wide-span portal frame steel structures providing column-free floor space for high-bay warehousing, distribution centers, and freight logistics.
3. Mining, Power Plants & Smelting Facilities
Heavy multi-story steel structures designed for harsh chemical environments, high thermal loads, and heavy material handling conveyors.
4. Aircraft Hangars & Shipyard Fabrication Bays
Clear-span steel building structures accommodating massive gate openings, high ceilings, and heavy-duty gantry crane rails.
Frequently Asked Questions (Product FAQs)
What design standards does ZOKECRANE follow for structural steel framing?
Our structural engineering team designs steel frames in strict compliance with international building codes, including Chinese GB 50017, American AISC/MBMA standards, and European Eurocode 3 (EN 1993), tailoring load calculations for local wind, snow, and seismic conditions.
How do you ensure the crane runway beam aligns properly with the steel structure?
Because ZOKECRANE is a professional crane manufacturer, we design the building frame and crane runway system simultaneously in 3D Tekla Structures. This ensures perfect coordination between crane wheel loads, bracket connections, rail seats, and column strength.
What surface finish should I choose: Epoxy Paint or Hot-Dip Galvanizing?
Multi-layer Epoxy Painting is cost-effective and highly suitable for indoor industrial workshops and standard atmospheric conditions. Hot-Dip Galvanizing (HDG) coats the steel in molten zinc, making it essential for harsh chemical environments, coastal marine zones, and outdoor exposed structures requiring long-term anti-rust protection.
Can ZOKECRANE supply sandwich panels and cladding materials together with the steel frame?
Yes. We provide complete pre-engineered building (PEB) packages, including steel frame structures, wall and roof cladding panels (EPS/Rockwool/PU sandwich panels or single steel sheets), skylights, gutters, downspouts, and doors.
Export & Logistics FAQs for International Buyers
Which international markets does ZOKECRANE export steel structure frames to?
ZOKECRANE industrial steel structures and crane systems are exported worldwide, serving industrial clients and EPC contractors in Russia, Uzbekistan, the Philippines, Bangladesh, Australia, Qatar, Tanzania, Singapore, Saudi Arabia, Brazil, Nigeria, and many other global markets.
How are large structural steel members packaged and loaded into containers?
Heavy H-columns, rafters, and crane runway beams are bundled securely with steel strapping and protective edge pads. Small structural fittings, purlins, bolts, and hardware are vacuum-sealed in plastic and packed in steel pallets or wooden cases for safe loading into 40ft HQ or Open-Top ocean containers.
What quality control documents accompany ZOKECRANE steel frame shipments?
Every shipment is accompanied by a complete quality assurance dossier, including ISO 9001 compliance, European CE certificates (EN 1090), EN 10204 3.1 Material Test Reports (MTR) for all steel plates, non-destructive weld testing reports (UT/MT), paint thickness sheets, and SGS third-party verification upon request.
What commercial shipping terms and manufacturing lead times do you offer?
We support standard international commercial terms including FOB, CIF, CFR, DDU, and DDP. Depending on total tonnage, building area, and surface treatment requirements, standard manufacturing lead times range from 25 to 45 business days.
Does ZOKECRANE provide site installation guidance for overseas projects?
Yes. We provide complete 3D Tekla assembly drawings, mark numbers on every steel member corresponding to the erection plan, and supply step-by-step installation manuals. Additionally, ZOKECRANE can dispatch experienced installation engineers to customer sites to supervise field assembly upon request.
