What To Know About Garage Doors

By Adriana Noton


A garage door is part of a garage, a place for vehicle storage. Generally garage doors are larger than average-sized doors because they require the passage of vehicles. These devices can be opened manually or by remote control.

Most overhead units are made up of several panels. These panels are hinged together and roll along tracks. Extension or torsion spring systems balance the weight of the structure. These gateways can be made from wood, aluminum, vinyl or steel. C. G. Johnson is credited with the invention of the upward-lifting door in 1921. Five years later he invented the electric garage door opener.

Single-panel gateways slide up and overhead to open. They are also known as monolithic doors because they have a single panel. The main disadvantage of these structures is how they open. When they are opened they swing outward, away from the structure. This can be inconvenient when it comes to parking. If a vehicle is not parked a few feet back from the structure, it could be hit when the door is opened. Furthermore, any object that is within the range of the structure could keep it from opening up fully.

Sectional gateways can have six or eight panels. These panels slide up and over to open. The structure occupies the same amount of space as monolithic structures, yet have more advantages. They do not swing outwards and therefore, do not require space outside of the garage in order to open. The structures are more reliant because every panel is separately attached to the track.

Roller units are made from corrugated steel. Sometimes they are constructed from other materials. Generally this is the case when impact-resistant material is not required or desired. Because of the strong material, they are capable of withstanding strong impact. They are commonly used on storefronts or at warehouse buildings.

Most of these devices are constructed from steel sheets made to resemble a raised panel wooden door. They are available double-skin, insulated and uninsulated material. Steel carriage doors have become quiet popular because they do not rot or weight a lot. They also come in a variety of designs.

Extension and tension spring systems are the two primary lifting mechanisms for these structures. Extension spring systems use a pair of springs that run alongside the horizontal tracks. Tension spring systems utilize one or two springs on a shaft that has cable drums on each side. When they are maintained, these springs can last for approximately three to seven years.

These gateways must be maintained. Once a month, at the least, they should be checked to make sure they are balanced and lubricated. If the garage doors Toronto structures are struggling to open and close it could be the sign of a bigger issue. Safety is just as important as maintenance. In fact, the two are related. Most serious injuries can be diverted, if the device and all of its parts are maintained and regularly checked for condition. Thousands of injuries related to incidents with these devices are reported on a yearly basis in America.
