Steel Framework, Eco-Friendly, for a Tailored Storage Shed – Assembled from Thin-Gauge Steel Members
Why Choose Us
Our solutions offer economical pricing, earthquake resistance, wind-load tolerance, anti-corrosion performance, and eco-friendliness—materials are fully recyclable.
Primary Framework
All steel parts are precision-fabricated in-house and then field-assembled using only high-strength bolted connections.
Roofing & Cladding Systems
Options include single-skin color steel, galvanized steel, or sandwich panels made of EPS, glass wool, rock wool, and PU.
Doors & Windows
We work with specialized partners to deliver customized, high-performance door and window solutions.
Full Accessory Packages
Every building comes with a complete set of necessary accessories—bolts, screws, sealing strips, flashings, and other required parts.
Customizable Add‑Ons
The structure can be easily fitted with overhead cranes, mezzanine floors (either plywood or concrete), and various other tailor‑made features.
About us
Project Applications – Real Uses
Industrial storage (factories & warehouses)
Expand your covered storage without permanent construction. Our sheds can be placed on existing asphalt or gravel. Used for raw material storage, equipment shelter, or mobile inventory.
Agricultural / farm use
Store hay bales, tractors, fertilizers. The galvanized frame resists ammonia corrosion. Choose high roof option for grain bins.
Commercial & retail
Extra inventory space for distribution centers, seasonal displays, or contractor tool storage. Double door option allows forklift access.
Residential / backyard
Garden shed, workshop, home gym, or pool equipment house. Custom colors match your house. Optional windows bring natural light.

Precision-Driven Manufacturing: Our Core Hardware for Steel Structure Excellence
Our production strength lies in a fully integrated ecosystem of advanced machinery:
-
Roll Forming & Cladding: Rock wool production line, Frame CAD light steel keel system, and a modern CNC C-shaped steel composite plate line.
-
Cutting & Drilling Precision: High-definition plasma cutters, 3D CNC cutting systems, intersecting line cutters, shearing machines, and CNC plane drills for complex geometries.
-
Welding & Assembly: SKLH gantry automatic welders, submerged arc welding machines, and plate rolling machines for heavy-duty connections.
-
Surface & Calibration: Shot blasting machines for surface prep, uncoiling lines, and SHHJ flange correction machines to ensure structural straightness.
Quality Assurance:
We enforce a "Zero-Defect" protocol through continuous in-process monitoring and final product inspection, ensuring every component meets the rigorous standards of international building codes.
Frequently Asked Questions
Q: Do I need a concrete foundation?
A: Concrete pad is recommended for permanent installation. For temporary or movable sheds, we offer screw pile or gravel pad options – please consult our engineering team.
Q: Can I assemble it myself without construction experience?
A: Yes – with two capable people and basic DIY skills. The manual and video guides cover every step. For large units (>24ft wide), we suggest hiring a local handyman for safety.
Q: How does light‑gauge steel compare to wood for insulation?
A: Steel conducts heat faster than wood, but we include thermal break pads at connection points and recommend insulated sheathing (EPS or polyurethane sandwich panels) for climate‑controlled storage.
Q: What is the maximum snow load?
A: Standard design: 85 psf (≈4.1 kN/m²). For heavy snow regions, we can increase section thickness or add extra trusses.
Q: Do you ship globally?
A: Yes. We ship from Quanzhou port. For North America and Europe we have dedicated logistics partners. Minimum order: 1 shed (no MOQ for storage units – we welcome small orders).
Q: How to request a custom quote?
A: Use our online configurator or email us with your desired dimensions, roof type, door location, and cladding preference. We will reply with 3D drawing and price within 48 hours.
