Special Spring Steel Belt For Rolling Shutter Door
Unlike other shutters that create 100% blackout conditions, Qompact’s perforated slat allows light in. This allows for egress (life safety) during emergencies, plus keeps your home cool.
The device comprises a hub (4) inserted and held against a fixed shaft that supports a series of rotating pulleys, around which the rolling shutter is rolled. It is peripherally provided with a drum (5) containing a toothed crown (7).
Heat-treated blue spring steel strip
Using heat-treated blue spring steel strip for a rolling shutter door allows manufacturers to create an end product that is durable and can withstand the heavy load demands of the door. This type of strip offers high tensile strength, fatigue resistance and ductility. It can also be customized to fit specific design requirements and meet industry certification standards. In addition, the strip’s surface can be coated or finished to improve its corrosion resistance.
The steel is formulated from premium raw materials and processed using advanced smelting techniques. This produces a material with consistent thickness and rigorous tolerance control, making it easy to process when manufacturing roller shutter components. The material is further treated with a special blue anti-corrosion layer to protect it from harsh environments, increasing its lifespan.
Rolling shutters provide protection against intruders without making a statement like security bars do. They are also effective in preventing damage from storms and hail, and can keep windows cleaner by keeping sand and dirt off of the glass. In the past, many homes located next to golf courses have experienced broken windows from stray golf balls. Rolling shutters are able to prevent this by protecting the glass from being damaged.
Ulbrich Stainless Steels & Special Metals is an ISO 9001:2015 and NADCAP certified custom manufacturer of a wide variety of cold rolled value added products. Their capabilities include slitting, toll processing, hydrogen atmosphere annealing, blanking, shearing, and metal testing services. They can provide blue tempered spring steel for rolling shutter doors in various widths, thicknesses, and lengths. Their quality assurance and technical support services are also available.
Customization
Heat treatment processes, including quenching and tempering, imbue our steel strip with high strength Special spring steel belt for rolling shutter door and excellent toughness. It also features precise dimensions and tolerance control, making it easy to process and ensuring a smooth fit with rolling shutter slats. In addition, the blue anti-corrosion layer protects against rust under harsh conditions and dramatically extends its service life.
Security:
Many people choose to install a shutter on their home because it prevents burglars from breaking glass windows and entering the building. These doors are made to withstand high winds and can be locked, so they provide an extra level of safety in addition to the traditional alarm system. The slats also help block out sunlight and reduce noise.
The slats of a rolling shutter are made from polyurethane or metal. They can be customized to meet your specific needs, including the width and length of each slat and the amount of insulation needed. They can also be paired with several different motors to create a custom solution that fits your space. These motors are available in battery and electric models, as well as solar options. They can be controlled with a remote or wired switches. You can even connect them to a smartphone app for increased convenience and security. The end bearing plates of the roller chain are prone to wear and may begin grinding against each other, which can cause damage and affect how well the rollup shutter works.
Durability
A shutter can resist a lot of abuse and still work for years. This is because its slats are made from durable material and protected with powder coating that resists corrosion. This allows them to stand up to weather damage, pests and vandalism. They can be opened manually by a hand crank or push-up operation, or with a tubular motor for large openings up to 180 square feet in size.
The spring steel belt is manufactured using scientific heat treatment technologies like quenching and tempering, resulting in high strength and excellent toughness. It also features precise dimensions and an anti-corrosion layer that is applied by chemical immersion. This makes it an ideal choice for rolling shutter door construction.
It is available in various widths, thicknesses and lengths and can be tailored to the specific needs of a customer. Its surface is also treated with a blue anti-corrosion layer that protects it from rust and other harmful elements.
The device of the invention is designed to compensate for a hinge or torsion spring by means of a compensation pawl (M) inserted outside the hub (4) and having a toothed crown (7). The pawl is intended to interfere with the forked head (8c) of the balancing pawl (2) in case of the torsion spring (M) breaking, thereby preventing the free, uncontrolled descent of the rolling shutter curtain.
Safety
When closed, Qompact slats nest into the industry’s smallest coil and don’t protrude from the window or door frame. This compact design allows you to enjoy the beauty of your home’s architecture and reduce the risk of mold and mildew. It also provides enhanced privacy and protection against water infiltration during hurricanes and strong storms.
The device of the invention consists in a bracket with a hub (1a) designed to be inserted and stopped against a fixed support shaft that supports the series of rotating pulleys around which the rolling shutter is rolled. The hub also houses a drum (5), characterized by an external toothed crown that cooperates with a balancing retention pawl.
Each of the pulleys has a box-shaped configuration, and each is fitted with compensation means that can balance the force exercised on each one by the weight of the rolling shutter. Annealed Steel Strip This counterbalance also helps minimize the effort needed to raise the shutter, both in manual and motorized operation.
The compensation means can be a torsion spring or a hinge spring, depending on the type of rolling shutter used. In the case of a torsion spring, the compression spring is attached to the end of the spring that extends from the pin (3) and is connected to the roller (M). The device further comprises an electric microswitch designed to immediately cut off the power supply to the motor in case the torsion spring breaks.
