1) In the table, the material is carbon steel (mild steel) , if the material is stainless steel and aluminum alloy.
2) Stanchion size: single rail manufactured according to design, double rail is 1020mm , and triple rail is 1,200 mm.
3) Column distance: mainly four kinds as 1000mm,1200mm,1500mm,2000mm.
4) Steel tube's size: subject to the design drawings confirmed by both parties.
Ball joint handrail have advantages such as attractive appearance, convenient installation, robustness, and good anti-corrosive property after treatment.
It is widely used in such industrial and construction engineering fields as sewage treatment plant, electric power, petrochemicals, machinery, waterworks, gardens, municipal roads, airports commercial and architectural applications.
Selections of Materials
1)Carbon Steel: This is the most commonly used material and is used in all types of applications.
2)Aluminum Alloy: Aluminum is usually used when weight or corrosion is an issue or in conditions where steel is unsuitable. Aluminum handrail is commonly used in sewerage treatment facilities and commercial and architectural applications.
3)Stainless Steel: Stainless Steel 304 or 316

Surface Treatment
1)Steel handrail is most cases Galvanized to protect against corrosion or available Powder Coated
2)Aluminium handrail can be Anodized Oxidation, Powder Coated or Mill Finish.
3)Stainless steel handrail is Electro-Polished.

Advantages
*Excellent corrosion resistance
