Garage Door Struts
WHAT IS A GARAGE DOOR STRUT?
A garage door strut is a steel reinforcement bar that runs horizontally across a garage door section, adding rigidity so the door can withstand wind pressure and the stress of an automatic opener. Minnesota Metals manufactures struts in 2-1/4" and 3" hemmed widths, in 20-gauge and 22-gauge galvanized and galvannealed steel, cut to length for distributors and manufacturers.

WHY DISTRIBUTORS & MANUFACTURERS CHOOSE MINNESOTA METALS
- Manufactured to spec — struts produced to your exact width, gauge, and length requirements, not generic stock only.
- Galvanized and galvannealed finish — corrosion resistance for long-term structural performance.
- Cut to length — no secondary processing needed on your end.
- Rush orders available — production flexibility when your supply chain is under time pressure.
- Wholesale/B2B only — pricing, minimums, and service built around distributor, manufacturer, and franchise volume, not one-off consumer orders.
STRUT PLACEMENT & WIND CODE COMPLIANCE
A strut should always be installed on the top section of a garage door when an automatic opener is attached - skipping this step can void the opener manufacturer's warranty. In regions with wind load building codes, 20-gauge struts are frequently required (rather than 22-gauge) to meet the higher structural rating. Minnesota Metals manufactures both gauges so distributors can stock the correct spec for each region they serve.
FAQ
Garage door struts are typically made from 20-gauge or 22-gauge steel. Minnesota Metals manufactures both, with 20-gauge commonly specified where wind code compliance requires the added strength.
20-gauge steel is thicker and stronger than 22-gauge, and is often required to meet wind load building codes in high-wind regions. 22-gauge is standard reinforcement for typical installations.
Yes. Struts are available in both galvanized and galvannealed finishes for corrosion resistance.
Yes. Minnesota Metals manufactures struts cut to the length specified by the distributor or manufacturer, rather than stock lengths only.
