Anonymous users2024-01-24The traditional balcony guardrail is made of iron, aluminum alloy and plastic steel as the main material, and now zinc steel profile is becoming the mainstream of guardrail materials, and it is also a hot product on the market, which is more cost-effective in strength, rust resistance, color change and oxidation resistance, easy to install and clean, and has a longer service life.
In family life, the elderly and children who need extra care the most when they are usually working outside, and the firmness of the balcony guardrail is directly related to life safety. A few days ago, there were frequent incidents of accidental falling of children, according to the standard of "Powder Coated Zinc Steel Protective Profiles for Construction" of the Provincial Quality Supervision Department. In the new standard, there are clear relative specifications for the zinc content, compressive index, anti-corrosion index and connection index of zinc steel materials.
Qualified zinc steel profiles, its zinc content shall not be less than 130 grams of square meters, otherwise its durability is greatly reduced, there is no so-called advantage, so users can ask the developer or manufacturer to provide an authoritative test report to inquire about this value when they are skeptical.
Generally speaking, the zinc steel balcony guardrail will adopt waterproof and anti-corrosion sealing process, if not, it will bring safety hazards to the elderly and children. Through news reports, CCTV also deliberately did a small experiment to identify whether the standpipe of their balcony is reliable, first the user pinched the inside of the standpipe connection with his fingers, and then pinched the outside of the standpipe connection of the guardrail with his fingers. If the inside and outside of the standpipe feel very hard or very soft, it proves that there is no waterproofing process.
Only when the outside of the standpipe is hard and the inside is soft, the guardrail does not have the potential safety hazard of breaking.
At the same time, according to the new standard, there will be a sealing sleeve on the inner groove of the joint of the zinc steel profile to prevent rainwater and other erosion into the inside of the profile. In addition, the guardrail product must be bolted and fastened, but the bolts must not be exposed.
There is also the easiest way to identify, whether the zinc steel profiles used in the balcony meet the new standard is to check whether the relevant identification and coding of the product meet the standard requirements. All the guardrail products produced by regular manufacturers have obvious trademark logos. If there is no trademark identification, it proves that the guardrail product is an inferior product.
