Importance in Garage Door:

Torsion springs are essential for the safe and efficient operation of garage doors. They are crucial for maintaining proper tension, ensuring balanced movement, and preventing accidents or damage.

Inspection Criteria:

During garage door inspections, professionals evaluate torsion springs for signs of wear, corrosion, or fatigue. Proper tension, alignment, and condition are vital criteria.

Common Issues and Failures:

Common problems associated with torsion springs include wear and tear, rust, and spring breakage. Failures can lead to imbalanced door movement, posing safety risks.

Maintenance and Repairs:

Regular maintenance involves lubrication, visual inspection, and spring adjustment by trained technicians. Spring replacement is a delicate task best left to professionals.

Regulations and Standards:

Torsion springs should meet safety standards set forth by organizations like the Door and Access Systems Manufacturers Association (DASMA) to ensure safe garage door operation.
