          一、圍擋材料種類

          1、 Types of enclosure materials

          1. 鋼管圍擋:由鋼管和連接件組成,可拼裝式安裝,搬運方便,使用壽命長。

          1. Steel pipe enclosure: composed of steel pipes and connectors, can be assembled for easy handling and long service life.

          2. 鋼板圍擋:由鋼板、支架、加強(qiáng)筋等組成,耐腐蝕、防火、防盜,但重量較大,不易搬運。

          2. Steel plate enclosure: composed of steel plates, brackets, reinforcement ribs, etc., it is corrosion-resistant, fireproof, and anti-theft, but it is heavy and difficult to handle.

          3. 網(wǎng)絡(luò)圍擋:由鋼絲網(wǎng)或鍍鋅網(wǎng)組成,透氣性好,適用于施工場地周邊環(huán)境要求高的項目。

          3. Network fence: composed of steel wire mesh or galvanized mesh, with good breathability, suitable for projects with high environmental requirements around the construction site.

          4. PVC圍擋:由PVC材料制成,輕便易搬,較實惠,適用于一些臨時性施工圍擋。

          4. PVC fence: Made of PVC material, lightweight and easy to move, with a relatively affordable price, suitable for some temporary construction fences.

          5. 塑料鋼圍擋:由PVC和鋼絲組成,具有較好的韌性和耐用性,可重復(fù)使用。

          5. Plastic steel fence: composed of PVC and steel wire, it has good toughness and durability, and can be reused.

          二、圍擋材料特點

          2、 Characteristics of Fencing Materials

          1. 鋼管圍擋:拼裝簡便,使用壽命長,較重的鋼管不易被破壞,經(jīng)濟(jì)實用。

          1. Steel pipe fence: Easy to assemble, long service life, heavier steel pipes are not easily damaged, economical and practical.

          2. 鋼板圍擋:具有防火、防盜、耐腐蝕的特點,但較高。

          2. Steel plate fence: It has the characteristics of fire prevention, theft prevention, and corrosion resistance, but it is relatively expensive.

          3. 網(wǎng)絡(luò)圍擋:透氣性好、重量輕、安裝簡便,但抗風(fēng)性和防護(hù)能力較差,一般適用于行人活動區(qū)域周邊。

          3. Network fence: It has good breathability, light weight, and is easy to install, but its wind resistance and protective ability are poor. It is generally suitable for the surrounding areas of pedestrian activities.

          4. PVC圍擋:具有輕便、易搬運、實惠等特點,但不耐用防護(hù)能力較差,所以一般適用于臨時性施工圍擋。

          4. PVC fence: It has the characteristics of being lightweight, easy to handle, and affordable, but it is not durable and has poor protective ability, so it is generally suitable for temporary construction fences.20211126091714124.jpg

          5. 塑料鋼圍擋:具有較好的韌性和耐用性,可重復(fù)使用,但相對較高。

          5. Plastic steel fence: It has good toughness and durability, can be reused, but the price is relatively high.

          綜上所述,圍擋材料有多種類型,各自具有不同的特點和用途。在選擇時,需要根據(jù)實際情況選擇合適的材料。

          In summary, there are various types of enclosure materials, each with different characteristics and uses. When choosing, it is necessary to choose suitable materials based on the actual situation.
