The existence of this problem, increased the maintenance of the road maintenance and the cost of materials and self-adhesive anti-cracking paste in the material properties to overcome the shortcomings of the traditional asphalt material.
Wood-plastic fence in addition to the needs of thinking modeling should not be suitable for climbing, the height should not be lower than the rules, the selection time, also need to think about the following points. The installation of the railing itself is for safety and aesthetics and other reasons, then we should pick the time when we should pay attention to the importance of these two points.
1, load-bearing: a lot of people are outside the fence structure, and thus protruding out of space, often steel fence into pots and other objects placed. Therefore, if it is to place the object, the purchase should consider the guardrail of the load-bearing capacity.
2, anti-corrosion: window fence, exterior balcony is necessary to have a balcony fence corrosion, as long as the anti-corrosion function to achieve the effect of durable protection, to resist the exposure and wind and rain at any time invasion. The anti-corrosion function of the balcony guardrail depends on its structure. The good guardrail is often composed of the inner and outer bottom structure. The general is that the substrate is the steel layer. The alloy layer is zinc, and the layer closest to the substrate is fine Alloy layer, the more chaotic its structure, its corrosion resistance is stronger.
