Introduction

A sectional door is a door that is divided into sections which are connected with hinges. As the door opens, the sections slide upward along the ceiling. This article outlines the core components of a sectional door and examines solutions offered by WELL LIFT Company.

Panel Construction

The panels are crucial structural elements of a sectional door. They are typically constructed from steel, aluminum, or wood. Steel panels are often preferred for their strength and durability. The panels are available in various thicknesses, typically ranging from 1.5 inches to 2 inches, and often feature an insulation layer with an R-value up to 17.5 for enhanced thermal efficiency.

Track System

The track system guides the movement of the panels. Made of galvanized steel, the tracks are usually available in 2-inch or 3-inch widths. Proper alignment and installation of the track system are critical to ensure smooth operation and prevent premature component wear.

Torsion Spring Assembly

The torsion spring assembly counterbalances the weight of the door, making it easier to open and close. These springs are rated by the number of cycles they can handle, typically ranging from 10,000 to 100,000 cycles. The choice of spring depends on the door's weight and frequency of use.

Lifting Mechanism

Lifting mechanisms can be manual or automated. Automated lifting involves a motorized trolley or chain-drive system that operates with motors of varying horsepower from 0.5 HP to 1 HP, depending on the size and weight of the door.

Control System

The control system allows users to operate the door safely and efficiently. Modern systems often include wireless remotes and can integrate with smart home technology. Advanced systems feature rolling code technology for enhanced security.

Weather Sealing

Weather seals are installed along the bottom, sides, and top of the door to prevent the ingress of water, dust, and other elements. The most effective seals are made from durable rubber or thermoplastic elastomers, ensuring longevity and effective insulation.
