The zinc steel guardrail balcony consists of a base material and accessories. The substrate of the zinc steel guardrail balcony is high-temperature hot-dip galvanizing material. The hot-dip galvanizing refers to putting high-quality steel into the zinc liquid pool of several thousand degrees. After soaking for a certain period of time, the zinc liquid will penetrate into the zinc-steel guardrail balcony of the steel. Composition of substrates and accessories. The base of the zinc steel guardrail balcony is high-temperature hot-dip galvanizing material. The hot-dip galvanizing refers to putting high-quality steel into the zinc liquid pool of several thousand degrees. After soaking for a certain period of time, the zinc liquid will penetrate into the steel.
It can form a special zinc-steel alloy. The surface of hot-dip galvanized material can be rusted for 30 years without any treatment in the field environment. For example, highway guardrails and high-voltage electric towers are all made of high-temperature hot-dip galvanizing materials. Its rust prevention lasts for 30 years, completely solving the problems between rust prevention, beauty and safety for many years.
The zinc steel guardrail balcony fittings adopt modified high-strength engineering nylon with a service life of up to 50 years. Its strength and hardness are much higher than ordinary steel materials. The pressure per square meter can withstand 183MPA and the tensile force of 2729MPA. Can withstand the high temperature below 220 °C without deformation and so on.
Advantages of zinc steel guardrail balcony:
1. The zinc steel balcony guardrail is environmentally friendly in application, does not pollute the environment, and solves the problem of pollution of buildings caused by common products.
2, good flexibility, the rigidity and flexibility of the substrate make the barrier products have better impact resistance.
3, the buried installation method and the floor plate installation, which saves your building base costs and saves land resources.
4, good decorative, rich colors, to meet the individual needs of different customers.
5, good weather resistance, salt spray resistance and damp heat resistance, suitable for use in different regions.
6, welding-free assembly design, installation is quick and easy.
7, four-layer anti-corrosion treatment, more than 20 years of service life, solve the problem of rust, powder, cracking and other problems of traditional products in a short time, eliminating the maintenance and renewal costs of zinc steel balcony guardrail products.
8. The surface of the electrostatically sprayed imitation pond porcelain process makes the zinc steel balcony guardrail products have good self-cleaning performance, and the rain wash and water spray can be as clean as new.

NSK manufacture a full range of deep groove ball bearings. These bearings are the most common type and are used in a wide variety of applications.
Single-Row Deep Groove Ball Bearings
Pressed Steel Cages
Single-row deep groove ball bearings are the most common type of rolling bearings. Their use is very widespread.
In addition to open type bearings, these bearings often have steel shields or rubber seals installed on one or both sides and are prelubricated with grease. Also, snap rings are sometimes used on the periphery. As to cages, pressed steel ones are the most common.
For big deep groove ball bearings, machined brass cages are used.
Machined cages are also used for high speed applications.
Extra Small Ball Bearings and Miniature Ball Bearings
Miniature and instrument ball bearings can be divided into two basic types, deep groove and angular contact. The first (deep groove) can be further divided into the following five classes depending on their design details:
Standard type
Flanged outer ring
Extended inner ring
Expanded type in which one ring has a radial thickness that is larger than normal compared with the bearing width.
Thin section type in which both rings are extra thin in the radial direction. They can also be classified as: open, shielded, or sealed.
Maximum-Type Ball Bearings
Maximum-Type ball Bearings contain a larger number of balls than normal deep groove ball bearings because of filling slots in the inner and outer rings. Because of their filling slots, they are not suitable for applications with high axial loads. types of bearings have boundary dimensions equal to those of single-row deep groove ball bearings of Series 6200 and 6300 respectively. Besides the open type, ZZ type shielded bearings are also available. When using these bearings, it is important for the filling slot in the outer ring to be outside of the loaded zone as much as possible. Their cages are pressed steel.
