According to the opening type, shutter doors can be divided into: manual shutters and electric shutters.
Manual Shutters: Utilize the torsion spring on the shutter's central shaft to balance the force, allowing the shutter to be operated manually.
Electric Shutters: Driven by a dedicated motor that rotates the central shaft of the shutter, enabling the opening and closing of the shutter. The motor automatically stops when the rotation reaches the preset upper and lower limits.
According to panel material, shutter doors can be divided into: aluminum alloy shutters, crystal shutters, stainless steel shutters, color steel shutters, PVC shutters, and so on.
Aluminum Alloy Shutters
The shutter doors, with their unique materials and structural design, can effectively prevent strong sunlight and UV radiation, completely mitigating the greenhouse effect created by sunlight indoors. They are suitable for various climates and weather changes and provide long-term protection for the indoor environment. Tests show that shutter doors can block up to 100% of sunlight and more than 95% of heat.
Color Steel Shutters
The door panels use color steel sheets, aluminum alloy sheets, or composite panels, with thickness selected according to the width of the door opening. Light-transmitting windows and small doors within the main door can be added as needed.
Crystal Shutters
Made from polycarbonate (PC bulletproof material) engineering plastics, the crystal shutter slats have waterproof and windproof properties. Aluminum alloy reinforcing ribs enhance protection, and options include frosted, transparent, and colored specifications.
Stainless Steel Shutters
These shutters feature a beautiful hue, smooth surface, horizontal embossed design, giving a layered and three-dimensional effect. The door surface is treated with baking paint, making the panels more durable. Multiple installation methods are available, allowing easy installation, fast construction, and cost savings through single-slats replacement in case of damage.
PVC Shutters
Also called rapid shutters, made from PVC material. They operate very quickly, reaching speeds of 0.6 meters per second. They can quickly isolate environments, ensuring dust-free air quality in workshops. They provide insulation, cooling, insect-proofing, windproofing, dustproofing, soundproofing, fire prevention, odor prevention, and daylight functions. Widely used in food, chemical, textile, electronics, supermarkets, freezing, logistics, and storage areas, they meet high-performance logistics and cleanroom standards, save energy, close automatically at high speed, improve operational efficiency, and create a better working environment.
According to installation type, shutter doors can be divided into: built-in wall or side wall (also known as inside the door opening or outside the door opening).
According to opening direction, shutter doors can be divided into: upward roll and side roll.
According to use, shutter doors can be divided into: ordinary shutters, windproof shutters, fire shutters, rapid shutters, and electric Australian-style (silent) shutters.
According to fire resistance rating, shutter doors are classified as follows
According to GB14102 "General Technical Conditions for Steel Shutters," ordinary steel shutters are divided into: F1, fire resistance duration 1.50h; F2, fire resistance duration 2.0h. Composite steel shutters are divided into: F3, fire resistance duration 2.50h; F4, fire resistance duration 3.00h.
