A floor spring is a mechanical door

closing device mostly used for glass doors along with patch fitting. Floor springs are

mostly used where both pull and push movement is required. The most prominent area where

floor springs are used is in Interior doors of a Business park, Malls, Hospital building.

features in common.

Invisibility

First, Floor Springs are suitable for aesthetic door systems. They must be virtually

invisible not to ruin the general look of the whole door. Because the aesthetic factor is

necessary, people produce many different types of floor springs to adapt with different

types of doors. They can change the material, size or color to achieve a final purpose: its

invisibility. However, their features also must comply with standards about size, material

to ensure safety.

Adaptability

Floor springs must be suitable for every type of door. There are some materials people

usually use to make doors. Glass doors are seemed to be very popular with people. Every

house, closed-restaurant, shop, kiosk, supermarket, mall, … uses glass as a popular

material for its door system. Besides, we can see that wood is also a favored kind of door

material. Another kind of material is Aluminum. Aluminum is a popular, affordable and

durable material in use for doors. Nowadays, many researches show that Fiberglass can be

the most ideal material. Evidence indicates that doors made from fiberglass have scratch

resistance capability for many years. Thus, aesthetic will be enhanced maximally.

Floor springs are especially ideal for big-sized doors. These doors are almost heavy

and big. People need more energy to push or pull these doors than smaller doors using door

handles. Therefore, selected floor springs must have certain requirements about closing

force, closing speed and latch action. To ensure adaptability of floor springs, all these

numbers must be adjustable. Besides, they also must comply with pre-registered standards

guaranty the quality as well as safety.

Affordability

Customer's budget always is an important thing. HeleH door lock has two types of

HeleH floor springs which are under a suitable price. The given price is not including

installation fee yet.

Another similar device is called door closers. A [url=http://www.heinda-cn.com/door-

closer/]door closer[/url], very simply, is a type of hardware that is used to close a door

either mechanically or automatically. It has developed into many different types like

Heavy Duty Door Closer

, Economical Door

Closer, Overhead Door

Closer and Concealed

Door Closer.

Most of the time, when we think of a door closer in the commercial door business, we

think of a surface mounted door closer that is installed to the door and frame with

fasteners. There is an arm that connects the body of the door closer to the “shoe”. The

body of the door closer can be attached to either the door or the frame, depending on

circumstances at the door, and the shoe will connect to the frame or door (opposite of how

the closer body is installed). So if the door closer body is installed to the door, then

the door closer shoe will be installed to the frame, and vice versa.

The main benefit of using a commercial door closer on a door is the range of controls

available to adjust the swing and motion of the door when it is used. These can help a

building stay secure, reduce air flow and save on air conditioning, and are used on fire

rated doors to help prevent the spread of fire and smoke by closing the door behind

occupants as they escape a building.

Using spring hinges as door closers is an economical option when budget is a concern.

These aren’t as fully adjustable as standard door closer hardware. Spring hinges can be

tightened to create more tension and ensure latching or they can be loosened to slow the

swing speed of the door. Besides this, there is not a lot of adjustments that can be made.
