How to Choose the Right Rolling Door Size? A Complete Guide to 100mm, 75mm, and 60mm Models

What Do 100mm, 75mm, and 60mm Mean?

The numbers "100mm," "75mm," and "60mm" refer to the height of the door slats (measured in millimeters) after they are formed. Each size has its own unique advantages and is suitable for different applications.

1. 100mm Rolling Door: Versatility and Durability

Golden Mountain’s Sunbeam 100mm rolling doors are top choices in the market, offering excellent stability whether used as traditional rolling doors or as wind-resistant doors. The 100mm slat height provides extra strength and durability. This model can be equipped with wind hook wheels to enhance its wind resistance and typhoon protection, making it ideal for regions prone to harsh weather, such as Taiwan. The 100mm model is suitable for industrial, commercial, or residential use, providing superior protection and the ability to withstand higher wind pressure, making it the perfect choice for high-demand areas.

Golden Mountain offers various material options:

o Stainless steel (also known as white iron): Available in thicknesses of 1.0mm, 1.2mm, and 1.5mm, offering excellent corrosion resistance and long-lasting durability.

o Galvanized steel and galvanized steel with baked enamel: Available in thicknesses from 1.0mm to 1.6mm, these materials offer good rust resistance and are more cost-effective.

2. 75mm Rolling Door: Traditional and Efficient

The 75mm rolling door has a slat height of 75mm and is commonly used for traditional rolling doors, making it a popular choice for both commercial and residential applications. Compared to the 100mm model, the 75mm door is lighter but still provides enough durability and strength to protect your property. For environments that don’t require additional wind resistance, the 75mm rolling door is an economical choice that meets everyday needs.

3. 60mm Rolling Door: Lightweight and Affordable Manual Option

The 60mm rolling door is a lightweight product with a slat height of 60mm, usually designed as a manual rolling door. It’s ideal for small shops or locations where the door is not frequently opened and closed. The 60mm door is easy to operate, and its simpler structure makes it more cost-effective, making it the top choice for small applications. While it is more economical, it still offers a basic level of protection.

Safety Features and Additional Functions for Rolling Doors

When selecting an electric rolling door, safety is a critical factor. Golden Mountain’s Sunbeam brand provides a variety of advanced safety features to give users peace of mind during daily operations.

1. Anti-Crush Safety Bottom Bar

The anti-crush safety bottom bar is an essential safety design that automatically stops and retracts the door for three seconds when it detects an obstacle, preventing injury to people or damage to objects.

2. Infrared Sensors

Infrared sensors can detect any abnormal situations during the operation of the rolling door. When the sensors detect an object, the door will automatically stop and reverse, preventing potential accidents or damage.

3. Anti-Collapse Chain Break Device

This safety feature activates if a gear tooth or chain breaks, preventing the door from suddenly falling. This ensures the safety of people and property in case of mechanical failure.

Diverse Material and Door Slat Design Options

Golden Mountain’s Sunbeam rolling doors not only offer various sizes and safety features but also allow for custom perforated slat designs. This enhances ventilation and aesthetics, providing consumers with a tailored solution for their specific needs.
