Precision engineering and proven corrosion prevention are essential for industrial-grade structural solutions. Galvanized Shed Frame systems from WECHEER Holding Group are made of hot-dip galvanized Q235B steel with a ≥80μm zinc coating, which provides a service life of more than 25 years in harsh outdoor conditions. WECHEER provides pre-cut, pre-drilled frame kits that range in length from 3 to 12 meters by utilizing its more than 40 years of experience in modular building and its six intelligent manufacturing bases with a production capacity of 200,000 pieces. Each frame is designed for easy assembly and compatibility with metal, polycarbonate, or timber cladding systems in residential, coastal, and agricultural settings. It consists of columns, rafters, purlins, base plates, and high-strength connecting gear.
Steel and zinc form a metallurgical connection by hot-dip galvanization. The entire frame is submerged in molten zinc at about 450°C during this procedure, creating many layers of protective alloy.
The thick layer of zinc serves as a sacrificial anode as well as a barrier. Zinc corrodes more readily than steel when exposed to moisture and oxygen, protecting your frame's structural integrity.
The surrounding zinc nevertheless offers cathodic protection even if the surface is scratched during installation or usage. Galvanized frames are perfect for high-humidity, coastal, and agricultural settings where rust would quickly deteriorate unprotected steel because of its self-healing feature.

Demonstrated Resistance to Corrosion under Severe Conditions
The typical G90 galvanization (about 76μm) is exceeded by the ≥80μm zinc coating. In salt-spray coastal areas and agricultural facilities exposed to animal waste, this additional thickness offers prolonged protection.
Pre-Designed to Ensure Error-Free Assembly
Each part is pre-drilled with connection holes, pre-cut to precise length, and labeled with assembly codes. Compared to field-cut systems, this precision minimizes waste, cuts down on on-site cutting, and speeds up installation by up to 40%.
Flexible Cladding Integration
Many wall and roof materials can be used with your Galvanized Shed Frame without any changes. Use the same connection points and trim elements when installing color-coated steel for weatherproof durability, polycarbonate for natural light, or wood for classic aesthetics.
Structural Integrity Over Time
With a minimum yield strength of 235 MPa, Q235B steel can sustain loads in the face of impact, wind, and snow. Repainting cycles that are necessary for bare or painted steel frames are eliminated by the galvanized finish.
Adaptable Range of Use
Ideal for pump-house enclosures, carports, equipment storage, small workshops, livestock shelters, and garden tool sheds. Compact 3 m x 3 m units and long 12 m clear-span structures are also possible with this modular design.

Operations in Agriculture
Prevent weather exposure for animals, hay storage, and machinery. The galvanized finish resists surface deterioration even after repeated washings and exposure to ammonia-rich conditions.
Workshops and Residential Gardens
Low-maintenance buildings that complement landscaping are advantageous to homeowners. Use clear polycarbonate for a bright potting area or pair the frame with timber paneling for a traditional garden shed look.
Properties Along the Coast
Standard steel corrodes more quickly in salt-laden air. WECHEER frames have a thick zinc coating that extends their service life much beyond painted or powder-coated competitors and offers proven protection in marine situations.
Commercial Parking and Storage
Companies who need carport constructions or weather-protected storage find long-lasting, affordable options. Because of its modular construction, the frame can be expanded in the future by adding bays without having to disassemble its current portions.

All vertical columns, horizontal purlins, roof rafters, diagonal bracing, base plates, and connecting hardware are included in the frame kit. Concrete footings or ground anchor points must be prepared in accordance with local wind and snow load regulations.
Columns are assembled on base plates, horizontal girts and purlins are connected, roof rafters are installed, diagonal bracing is added, and cladding is applied in a logical order. Two persons can install most 6 m x 4 m frames in a single day.
Each shipment is accompanied by comprehensive assembly drawings with part numbers. Bolt-through or self-drilling screw connection points do not require welding equipment or specialized tools.

Frame components are packaged by WECHEER in bundles fastened with steel strapping. Brackets and hardware come in separate boxes with comprehensive packing lists. Multiple frame kits can fit in standard containers, which lowers shipping costs for large orders.
The destination and customization requirements determine the delivery schedule. Usually, stock-size frames are shipped in 7–10 working days. Production lead times for custom spans or customized coatings could be 15–20 days.
Q: How is the steel frame protected by galvanization?
A: thick layer of zinc is applied during hot-dip galvanization, which prevents rust by acting as a barrier against moisture and oxygen. Through sacrificial corrosion, the zinc continues to shield the surrounding steel even after it is scratched.
Q: What is the zinc coating's thickness?
A: minimum zinc coating of 80μm is a feature of our product systems that offers long-term corrosion protection appropriate for outdoor and coastal conditions.
Q: Is it possible to utilize the frame close to the sea?
A: Yes. Because of its exceptional resistance to salt corrosion, galvanized steel is especially advised for coastal regions. Additional protective coatings can be used for severe sea exposure.
Q: What kind of cladding complements this frame the best?
A: Color-steel sheets are waterproof and long-lasting. Natural light can pass through polycarbonate panels. Traditional aesthetics are provided by timber planks. The requirements of your application and your financial situation will determine your decision.
Q: Do I require a professional installer?
A: Skilled do-it-yourself installation is made possible by the pre-drilled, labeled components. However, hiring a local contractor guarantees correct alignment and connection torque criteria for bigger spans or if you are not familiar with structural assembly.
Q: What kind of foundation is necessary?
A: For larger constructions and permanent installations, concrete footings are advised. For smaller sheds in stable soil, ground anchor systems are effective. Local wind loads and frost depth requirements should be taken into consideration while designing a foundation.
