常見的護欄材質有鋁合金、PVC、鋅鋼、鐵、石材、玻璃、木材等等。不同的位置需要不同的護欄材質。譬如別墅陽臺、露臺一般可以選用石材、不銹鋼、鋅鋼等，如果是封閉陽臺，可以用木材、玻璃等；而花園護欄一般可以選用不銹鋼、鋁合金和鋅鋼等。
        一、盡管不銹鋼是常見的護欄材料，但以往大家可能都認為不銹鋼只有銀色，其實不然。經過工業(yè)加工，不銹鋼可以有多種顏色，比如常見的黑金色，還有紫金、香檳金、咖啡金、寶石藍等各種顏色。相比于鋁合金，不銹鋼耐腐蝕、耐高低溫，性能更穩(wěn)定，安全性更高，更不易變形，同時也昂貴一些。
        二、石材中，仿大理石經常被用來打造別墅護欄。仿大理石相比大理石更容易蘇醒，價格更低，而且具有良好的透氣性和防水性。
        三、鋅鋼（鋁合金）是金屬材質中顏色豐富的一種，它有良好的柔韌性，容易塑形，而且安裝簡單，甚至不用焊接就可以輕松裝好護欄。
        四、PVC（聚氯乙烯?。┳o欄又被稱為塑鋼護欄，就是在塑料里加入合適的型鋼，以保證護欄穩(wěn)固性的一種護欄材質，常用作室外圍欄、花園圍欄等。PVC不用噴涂油漆，不需要特別護理，它沒有尖銳的棱角，硬度也比較低，而且抗老化性。

Common barrier material of aluminum alloy, PVC, zinc, iron, steel, stone, glass, wood, etc. Different position need different barrier material. Such as villa, balcony, terrace can generally choose stone, stainless steel, zinc, steel and so on, if it is closed balcony, you can use wood, glass, etc.; And the garden fence can generally choose stainless steel, aluminum alloy and zinc steel, etc.

One, while stainless steel is a common barrier material, but in the past people might think stainless steel only silver, actually otherwise. Through industrial processes, the stainless steel can have a variety of colors, such as the common black and gold, and the purple and gold, champagne gold, coffee, and various colors such as gold and sapphire blue. Compared with aluminium alloy, stainless steel corrosion resistance, corrosion resistance, high and low temperature performance is more stable, higher security, more is not easy to deformation, as well as expensive.

Second, stone, imitation marble is often used to build villas guardrail. Imitation marble, marble is more than twice as likely to lower prices, and has good air permeability and water proofing property.

Three, zinc steel (aluminum alloy) is a kind of metal material rich in color, it has good flexibility, easy to shape, and simple installation, even without welding can be easily installed fence.

Four, PVC (polyvinyl chloride) fence is also known as plastic barrier, is to join the appropriate sections in the plastic, guardrail to ensure the stability of a kind of barrier material, commonly used for outdoor fence, garden fence etc. PVC without spray paint, do not need special care, it has no sharp edges, hardness is low, and aging resistance.
