Not All Steel Doors Are Alike05/25/2015 Back To Blog
There are steel garage doors and then there are steel garage doors! You might own one, your neighbor might own one but they might be completely different in terms of how long they'll last and what they offer. If you're wondering why they should behave differently if they're installed in the same neighborhood, think of little personal details! First of all, they're not only affected by the weather but by a number of other factors, too. Second, they're not all made of the same material even if we're still talking about steel.
How is steel different
Steel is steel but not exactly the same when it undergoes some processing. It would be different to have an overhead door made of plain steel from a door made of zinc coated steel. Then again, galvanized steel is still different in different occasions. It would depend on how it was processed and the quality of materials used. Zinc coated steel would last longer because the zinc coating would protect steel hiding underneath. Even if it's cracked after many years due to bad temperatures or lack of garage door maintenance, it would take time before steel would start to be affected by the climate.
Steel doors would also differ in terms of thickness. Whether they're thicker or not, some possess insulation materials and, thus, provide energy efficiency, too. The right powder coat in terms of quality but also frequency of garage door painting would also affect the longevity of the door. The strength of the door would also depend on the steel used. Is it made of low gauge steel – like 24-gauge? In this case, it would be stronger. Take insulated doors, for example. They're usually more durable since they often consist of two or more layers of steel panels and each panel is made of 24-gauge. Having two or three 24-gauge steel panels for sectional doors make the difference!
