Product Description:



Floor Spring is used for glass door, and they can be used together with door clamp. Floor Spring can be opened with double sizes, and on this point, it is different from that of door closer, which can just be opened by one size.  The key of technique lies on the loading seat under the main bearing, which decides the level of loading on the floor spring. Usually it can be opened from 300thousand or 1million times





u  Applicable for glass doors, wooden doors and the glass doors of metal frame and wooden frame.

u  Floor spring comply to EN 1154 and GB standard , and fire-rated EN1634 standard.

u  Maximum 500000 cycles tested without damage or maximum 7 years guarantee.

u  Double ways opening with smoothly movement, hold-open at 90°.

u  Closing speed and latching speed adjustable, latching point accurately at 0°

u  Stainless steel cover plate, satin or mirror surface available.

u  High quality casting iron floor spring body with 2 layers anti-rust coating.

u  All spindle types available for different countries.

u  Germany hydraulic machine oil and sealed rings, keep perfect working in cold temperature.

1.      Draw lines and make floor spring pivot center and door-nip pivot coincide with each other.

2.      Drill holes on the floor according to the instructions. The sizes of the holes must tightly match the floor spring.

3.      Place the floor spring into the holes and position it.

4.      Raise the door leaf installed with door-nip, and insert the floor spring pivot into the hole of the door leaf.

5.     Adjust the screws at three directions. Make them vertical and the upper and lower pivot center coincide with each other.

6.      Adjust the speed of door closing.

7.      Put the decoration cover on the floor spring.

Q:What's the manganese content of spring steel?
Refer to Baidu Encyclopedia: in accordance with its manganese content is divided into general manganese content (mass fraction) (0.50%~0.80%), such as 65, 70, 85 and higher manganese content (mass fraction) (0.90~1.20%), such as 65Mn two categories.
Q:Can springs be used for support?
One point, the spring you choose to bear the force is higher than the gear weight pressure, if higher than, then the spring to withstand 0. Unless the heat changes, the spring steel is denatured. Long periods of rust change can also make a difference. Deal with the above two points. 0 pressure spring does not exist short pressure
Q:How about the size of the elasticity?
Spring elastic deformation, the elastic limit, the elastic force with the elongation of the spring (or shorten) is proportional to the length (or the length of the spring and the pulling force is proportional to F=-kx (), or delta F=-k delta x). Where k is called the coefficient of stiffness (as a coefficient of rigidity or elasticity) of a spring, in numerical terms equal to the elasticity of a spring when it is stretched (or shortened) in unit length. The unit is Newton per meter, and the symbol is N/m. The K value is related to the nature of the material. The difference between the stiffness and stiffness of springs is that they have different stiffness coefficients. Moreover, the stiffness coefficients of different springs are generally different. The expression in the sign spring caused by its elongation (or compression) in the opposite direction. The law was discovered by British scientist Hooke, known as Hooke's law.
Q:How to choose spring steel material?
The cold plastic deformation of the cold drawn spring material is high, and most finished steel wires have reached the required mechanical properties when the steel mill is out of the factory. The surface quality of the steel wire is high, and the spring manufacturing process is simple. For springs of medium or small spring or high fatigue life, the cold spring or cold drawn spring or steel wire or strip shall be selected as far as possible. Carbon spring steel wire (group I, group II, group II A, dish group) and important uses of 65Mn spring steel wire during the cold drawing process caused in large residual stress, the larger the size change after low temperature tempering, and thus affect the dimensional accuracy of the spring. This kind of steel wire should be used preferentially for the tension spring with small bending radius and the compression spring with smaller diameter of steel wire. Oil tempered steel wire for residual stress, cold forming, precision spring is easy to control, low temperature tempering after the size change is very small, especially because there is no residual stress relaxation resistance than carbon spring steel wire lead quenching and cold drawing good. For the spring with higher size precision and the thicker diameter of spring steel and the good spring resistance, the oil quenching and tempering steel wire shall be used.
Q:Is spring steel manganese steel?
Manganese steel and spring steel are the names produced under different classifications. The spring steel is classified from its use, and manganese steel is classified from its constituents. Spring steel also contains manganese, which is a kind of manganese steel.
Q:The glass door spring is broken. How much would it cost to change it?
The price of the spring itself is about 200-800, plus part of the labor cost. After all, it's very expensive. There are about 150 of the spring, but the quality is not good, or safety first. Labor costs are probably about 120. Specific prices should be based on your actual situation, you and the master speak.
Q:Physics high school. Why does a spring fall to the lowest point and the acceleration a must be greater than the acceleration of gravity g ah. Seek expert
According to the conservation of mechanical energy, the object should be a free fall motion at the upper end of the spring
Q:What kind of material does spring have?
Alloy spring steel: alloy spring steel is used to make spring or other elastic parts of steel. Spring is generally under alternating stress, the fatigue failure is a common failure forms, therefore, alloy spring steel must have high yield and yield ratio (s/ b) and the anti fatigue performance of elastic limit, and to ensure that the spring has enough elastic deformation ability and can withstand greater load. At the same time, alloy spring steel also requires a certain plasticity and toughness, a certain hardenability, not easy to decarburization and not overheating. Some special springs also require heat resistance, corrosion resistance, or a stable elasticity over a long period of time. Medium carbon steel and high carbon steel can be used as springs, but because of its hardenability and low strength, it can only be used to make smaller cross-section, less force of the spring. Alloy spring steel can produce important spring with large cross section and high yield limit
Q:What are the categories of springs?
A spring is a mechanical part that uses elasticity to work. Parts made of elastic materials deform under external force and are restored to original shape after removal of external forces. Also made as a spring". Usually made of spring steel. The type of spring is complex and varied. According to the shape, there are mainly spiral spring, scroll spring, plate spring, special-shaped spring and so on.
Q:The glass door spring is generally guaranteed for several years
,expect a warranty to ensure the quality is not very reliable.
