  PVC護(hù)欄優(yōu)勢(shì)

  Advantages of PVC guardrail

  1、顏色漂亮、艷麗,表層光滑明亮,是裝飾設(shè)計(jì)作用的護(hù)欄產(chǎn)品系列。

  2、不用漆料和維修保養(yǎng)。

  2. No need for paint or maintenance.

  3、有充足的抗壓強(qiáng)度。具備比木料好很多的_度和延展性,護(hù)欄橫杠及其超重型護(hù)欄均襯有熱鍍鋅異形不銹鋼板材開(kāi)展提高,或覆蓋特殊PVC材料,使護(hù)欄兼具不銹鋼板材的_度和PVC的美觀大方。

  3. Has sufficient compressive strength. It has much better elasticity and extensibility than wood. The guardrail crossbar and its super heavy guardrail are lined with hot-dip galvanized irregular stainless steel sheet for improvement, or covered with special PVC material, making the guardrail have both the elasticity of stainless steel sheet and the beauty of PVC.

  4、組裝簡(jiǎn)單、便捷。選用權(quán)的承接式聯(lián)接件開(kāi)展組裝,可進(jìn)一步提高組裝速率。

  4. Easy and convenient assembly. Using patented connectors for assembly can further improve the assembly speed.

  比木料堅(jiān)毅,且更富延展性和高耐沖擊性能。

  More resilient than wood, with greater ductility and high impact resistance.

  5、對(duì)人會(huì)、畜沒(méi)害,即使不經(jīng)意碰觸護(hù)欄也不會(huì)像鋼、鐵護(hù)欄那般致傷。

  5. It is harmless to humans and animals, and even if you accidentally touch the guardrail, it will not cause injuries like steel or iron guardrails.

  6、使用期限長(zhǎng)。PVC護(hù)欄的確保使用期限為15年以上。因?yàn)檫\(yùn)用了特殊秘方和專用型的抗光穩(wěn)定劑,因而不容易退色、變黃、蛻皮、風(fēng)摧、裂開(kāi)、出泡、和生蟲(chóng)。

  6. Long service life. The guaranteed service life of PVC guardrails is over 15 years.

  7、因?yàn)椴挥镁S護(hù)保養(yǎng),了保護(hù)監(jiān)管的不便而使綜合性成本費(fèi)小于木制和鋼材護(hù)欄。

  7. Because it does not require maintenance and eliminates the inconvenience of protection and supervision, the overall cost is lower than that of wooden and steel guardrails.

  PVCpvc異型材的能源消耗僅為鋼材的1/14,因而它是一種產(chǎn)品。

  The energy consumption of PVCPVC profiles is only 1/14 of that of steel, making it an environmentally friendly, energy-saving, and eco-friendly product.
