The Exhibitions in 2018

hinged door, medical automatic door, stainless steel automatic door, electric folding gate, crystal rolling door, electric roller shutter of various materials, and parking lot series.

In March 20-22,2018, we attend the R+T ASIA 2018 SHANGHAI. It is good chance for us to communicate with our customers face to face. We met many customers,our regular cutomer and new customers.

Now we are going to attend the the Fersh Food Asia 2018 in Shanghai New International Expo Centre. We are waiting for you in Shanghai.

Our company has more than 13 years history and we passed CE,SGS and IS9001. Our best sell product is High Speed Door.

High Speed Door are door systems, mainly used in industrial applications. They are technical enhancements of the generally known sectional doors, PVC fabric doors or roller shutters. The main difference is that the durable construction provides a higher operating speed and they are able to sustain a higher number of cycles (opening and closing cycles) and require lower maintenance and repair cost. Depending on the intended field of application, horizontal or vertical operating door types are available.

High-speed doors are usually used wherever goods traffic occurs and where the doors have to fulfill special requirements. In the food and beverage industry, or Medical industry for example, special climatic conditions have to prevail; short opening and closing times reduce cooling loss, avoid airflow and enable a smooth operating procedure. They can also be designed in larger dimensions for the mining and aircraft industries.

Our high speed door require high strains, caused by the high operating speed (up to 4 m/s) and the frequency of openings, have to be taken into account during construction. In the same way, basic conditions like size and installation location add up to considerable requirements regarding safety and control technique.

A unique "roll-up" system generally defines a high-speed door from a conventional roller door. The door's main objective is to produce a high opening speed and the guiding system must allow smooth operations with minimal friction. Effortless movement will ensure the longevity of the door's moving parts and operating soundness. The latest versions of high quality high-speed doors use a spiral guiding system, thus keeping the door blade apart through a whole operating cycle, ensuring effortless movement of the door's roller devices in the guiding system and contributing to the excessive high speed. Excessive because these doors, by opening so fast and closing very slowly, are just trying to avoid getting their rigid closing edge caught by a forklift, at the expense of the insulation.

A counterbalance system generally forms part of the door's construction. This is designed with spring or weight mechanisms in the side frames, ensuring an emergency opening function and aiding to the opening speed.
