Railings are widely used in our life to multiple occasions, there is spacing between railings, and so what should be the safe spacing between railings on different occasions?
1. Type of railings:
The requirements for different railings are certainly different. And the railings may be divided into several types according to the type of the building in which the railing is located.
(a) Industrial building railings. When the benchmark height is less than 2m, the protective railing shall not be less than 900mm, more than 2m and less than 20m, railing height shall not be less than 1050mm; not less than 20m, and railing height shall not be less than 1200mm.
(b) Railing of civil buildings. Airport height shall not be below 24m, the railing height shall not be less than 1.05m, the airport height of 24m and above 24m, and the railing height shall not be less than 1.10m;
(c) Balusters of residences, nurseries, kindergartens, primary and secondary schools and special activity places for children, cultural and entertainment buildings, commercial service buildings, sports buildings, landscape buildings and other places allowing children to enter the activities. When vertical rods are used as railings, the net distance between the poles shall not be more than 0.11m.
2. The indoor and outdoor standards of railings are different:
(a) Indoor railing. The height of the interior stair decoration, the standard should be 90cm, of course this data can be changed according to the actual situation. After all, each family height is different, when the length of the stairs is more than 5 meters long, the height of the stair handrail can be appropriately raised to 100cm.In addition, if there is a child in the home, for safe reasons, but also should be the height of the stair armrest, set as 100cm is better.
(b) Outdoor railing. When the air height is less than 24 meters, the height of outdoor common stair handrail shall not be less than 105cm. When the air height is more than 24 meters, the height of outdoor stair handrail shall not be less than 110cm.
3. The provisions of the relevant specifications:
General Rules 6.6.3.4 for Civil Buildings Design stipulates that the railings of residential buildings, nurseries, kindergartens, primary and secondary schools and children must be in the structure to prevent children from climbing. When vertical poles are used as railings, the net distance between the poles shall not be greater than 0.11m; (this is a mandatory provision)
“General Rules 6.6.3.5 of Civil Building Design” stipulates that: cultural and entertainment buildings, commercial service buildings, sports buildings, landscape buildings and other places allowing children to enter the activities, when the vertical rods as railings, the net distance between the poles shall not be more than 0.11m.; (This is non-mandatory.)
4. The development prospect of the guardrail:
At present, the development of China’s guardrail industry is relatively slow, and for the development and application of the brand is less. Many railing manufacturers do not have their own brands, more guardrail manufacturers are silently doing for foreign big customers, buyers OEM or OEM business. Young China guardrail in the gradual growth, in terms of production capacity, China can be considered as the world’s most, but the brand, the core technology, I am afraid that our gap is still quite big. The largest guardrail market is at least now not at home, but in the economic strength of the more developed European and American countries, because their market after hundreds of years of baptism, with perfect production technology, sales channels and brands, market norms, perfect standards, high industrial maturity.
