A, indoor staircase handrail height specification
Indoor staircase decoration height, the standard is 90cm, of course, this data can be changed according to the actual situation. When the length of the staircase is more than 5 meters long, the height of the staircase handrail can be raised to 100cm. in addition, if there are small children at home, for safety reasons, the height of the staircase handrail should also be set at 100cm for the best.
Two, outdoor staircase handrail norms
When the height of the air in the 24 meters below, outdoor *** with the staircase handrail height should not be less than 105cm, when the height of the air in the more than 24 meters above, the height of the outdoor staircase handrail height should not be less than 110cm.
Expanded Information:
Stairhandrail is the support bar of the stair guardrail. Stair handrail according to the material to be categorized as: stair polymer handrail, stair iron handrail, stair stainless steel handrail, stair glass handrail, stair solid wood handrail, stair copper handrail.
There are some special staircase handrails: staircase luminous handrails.
Staircase handrail material
Iron
High-grade material
1, material: the national standard Q-235A grade steel.
2, welding process: using carbon dioxide gas shielded welding. (Welding point uniformity, gas-tight performance, good firmness) electrodes.
Iron process: hand forged iron.
3, surface treatment:
Hot-dip galvanizing process
Electrostatic spraying: no thinning, construction of the environment is pollution-free, non-toxic to the human body; excellent quality of the coating appearance, adhesion and mechanical strength; spraying construction of a short curing time; the coating of corrosion and abrasion-resistant ability to a lot more; do not need a primer; easy to construct, the technical requirements of the workers are low; the cost of less than the spray painting process; Some construction occasions have been clearly proposed must use electrostatic spraying process treatment; electrostatic powder coating process will not appear in the paint spraying process common flow phenomenon.
Mid-range material
1.Material: non-standard Q-220B grade steel.
2. Welding process: using manual electric welding technology.
Iron craft: mostly use cast iron or ordinary profile bending.
3, surface treatment:
Cold galvanized or not galvanized.
Paint
are used in Tianjin, Wuxi and other areas of production such as lighthouse paint.
Wood
The solid wood staircase handrail is made of all solid wood materials, and the most commonly used solid wood handrail materials in China at present are beech, oak, pear, teak, sapele, camphor pine, and so on. The shape of solid wood staircase handrail is mainly mushroom-shaped, oval, round, square.
Solid wood staircase handrails are generally supporting in the hotel lobby and other public **** place of the guardrail handrail or and solid wood staircase supporting the use. The wood texture and touch of solid wood stairs is irreplaceable by other materials.
New materials
Polymer stair handrails are commonly known as environmentally friendly wood, excellent wood, is widely used in developed countries of the new material, this product is a breakthrough in the low-carbon era of new materials, than the daily plastic and solid wood is tougher, more low-carbon, more powerful, can be replaced by wood, aluminum profiles and stainless steel, and other traditional materials handrails. It combines the various advantages of wood in one, but abandoned all the bad solid wood products.
With good processing performance, low manufacturing costs, corrosion resistance, insulation and other good features. With high strength, temperature resistance, corrosion resistance, insulation, insulation and other properties. With excellent flame retardant, abrasion resistance. Natural texture, green and safe, fresh and gorgeous, soft touch.
