Product Specification

Heavy-Duty Torsion Spring | 0.1-10mm Steel for Garage Doors

Product Description

Our Heavy-Duty Torsion Spring is engineered for high-cycle performance and maximum torque efficiency. Manufactured from premium-grade carbon steel or oil-tempered wire, these springs are designed to handle the rigorous demands of overhead garage doors, industrial shutter systems, and heavy mechanical counterbalances.

With a wire diameter range from 0.1mm to 10mm, each spring is precision-coiled to meet exact tension requirements. To ensure an extended service life, we utilize advanced heat-treatment processes that stabilize the steel's molecular structure, preventing premature sagging or breakage. Whether for residential garage door repair or large-scale industrial gate manufacturing, our torsion springs deliver the reliable rotational energy and durability needed to keep heavy systems moving safely and smoothly.

Features

• Extended Service Life: Engineered to withstand high-frequency cycles without loss of tension or structural integrity.

• Wide Diameter Range: Available in wire sizes from 0.1mm to 10mm, providing solutions for both micro-electronics and heavy industrial doors.

• Superior Material Strength: Crafted from high-tensile oil-tempered steel or stainless steel for maximum load-bearing capacity.

• Corrosion Resistance: Optional surface treatments like black coating, galvanization, or powder coating to protect against oxidation in outdoor environments.

• Precision Engineering: Computer-controlled coiling ensures consistent pitch, diameter, and leg angles for seamless installation.

Technical Parameters

Applications

These springs serve as critical components in various high-torque environments:

• Garage & Industrial Doors: The primary power source for counterbalancing the weight of residential garage doors and heavy commercial rolling shutters.

• Automotive Systems: Integrated into trunk lids, hood hinges, and heavy-duty tailgate lift-assist mechanisms.

• Agriculture Equipment: Used in heavy machinery gates, hatches, and tensioning arms for harvesters and tractors.

• Loading Docks: Essential for dock leveler lip hinges and overhead warehouse door systems.

• Industrial Furniture: Heavy-duty hinges for industrial storage cabinets, tool chests, and heavy equipment lids.

Customization

The METS Team specializes in delivering bespoke torsion solutions tailored to your unique mechanical challenges:

• Custom Leg Design: We can manufacture complex leg shapes including bends, loops, or threaded inserts to match your specific assembly.

• Specific Torque Requirements: Our engineers provide calculations to ensure the spring rate perfectly balances your specific load.

• Material Selection: Choose from specialized alloys if your application requires high-temperature resistance or non-magnetic properties.

Support and Services

• Technical Design Support: Access to our engineering team for spring rate calculations and material optimization.

• Professional Greeting: All formal inquiries are handled with the respect you deserve, beginning with "Dear Sir/Madam".

• Quality Testing: Every batch undergoes stress testing and salt spray testing (if coated) to ensure international quality standards.

• Documentation: We provide Material Certificates and Full Dimension Inspection Reports upon request.

Packing and Shipping

• Industrial Grade Packaging: Each spring is lightly oiled to prevent rust and packed in high-strength wooden crates or heavy-duty cartons to prevent deformation during transit.

• Global Export: We handle all export documentation and offer flexible shipping via Sea Freight, Air Cargo, or International Express (DHL/UPS/FedEx).

• Clear Labeling: All packages are labeled with part numbers, specifications, and batch codes for easy traceability.

FAQ

Q: What information is needed for a quote?

A: Please provide wire diameter, outside diameter, total coils, leg length/shape, and the required material or surface treatment.

Q: Can you provide Left Hand and Right Hand wound springs?

A: Yes, we manufacture both directions to accommodate standard garage door setups which typically require a pair of opposing springs.

Q: Do you offer samples for testing?

A: We can provide prototypes for verification; please contact us to discuss the specific parameters for your sample.

Q: How do you guarantee the life cycle of the spring?

A: Through strict material selection and controlled tempering, we ensure our springs achieve the rated cycles without fatigue failure, providing an extended service life.
