1, zinc steel
Zinc steel is one of the most suitable materials for balcony guardrail. Because of its strong load-bearing, good durability, rust and corrosion resistance, affordable price and long service life, it is favored by all kinds of construction contractors. So now most residential buildings are using this kind of zinc-steel balcony guardrail. And it is a common material with affordable price and beautiful appearance.
2, stainless steel
Stainless steel is also one of the most suitable materials for balcony guardrail. However, compared with the zinc-steel balcony guardrail, it is easy to deform because of its few colors, so its application scope is general.
3. Aluminum alloy
Aluminum alloy balcony guardrail is more expensive than the above two materials, so many large buildings rarely use aluminum alloy as balcony guardrail. This material is expensive, easy to scratch and has high maintenance cost, so it is not commonly used.
