Do you want to choose a beautiful and practical enclosure for a construction site with limited funding? Do you know what kind of fence is suitable for your engineering needs? The selection of enclosure includes the following factors: construction site construction and material selection are crucial. Currently, there are three main types of enclosure in the national market.

类、金属围挡：又称彩钢围挡、金属无缝围挡，龙骨扣彩钢围挡，

The first type, metal fence: also known as color steel fence, metal seamless fence, keel buckle color steel fence,

金属围挡：这类围挡主要材料还是彩钢板组成，金属围挡标准版（2米高、3.6米宽、板厚0.3mm）影响还是彩钢板的厚度为主，优点：金属围挡强度高于PVC围挡、美观度较高、光洁度较高，使用年限也能达到5年以上。特别是经过改良后的新型龙骨扣彩钢围挡，采用1.2厚的G型钢做龙骨，大大增强了围挡抗风强度，安装更简单方便。

Metal fence: This type of fence is mainly composed of color steel plates. The price of the standard version of metal fence (2 meters high, 3.6 meters wide, and 0.3mm thick) is mainly influenced by the thickness of color steel plates. Advantages: Metal fence has higher strength than PVC fence, higher aesthetics, higher smoothness, and can be used for more than 5 years. Especially the improved new type of keel buckle colored steel fence, which uses 1.2 thick G-shaped steel as the keel, greatly enhances the wind resistance strength of the fence and makes installation simpler and more convenient.

金属围挡的特点

The characteristics of metal fences

新型金属围挡全部采用金属材料，表面经过静电喷涂等特殊处理，耐高温，耐腐性，不颜色靓丽不褪色，防虫防潮的特点。使用寿命长，材料绿色，可回收可循环使用。

The new metal enclosure is all made of metal materials, with special treatment such as electrostatic spraying on the surface, which is resistant to high temperature, corrosion, no color, no fading, and has the characteristics of insect and moisture resistance. Long service life, green and environmentally friendly materials, recyclable and recyclable.

金属围挡的立柱、横梁、斜拉杆、挡板、横撑加强筋等部件能够快速安装，标准化拼装。生产效率高，运输方便，极大程度上降低了围挡的采购成本。

The components of the metal enclosure, such as columns, beams, diagonal braces, baffles, and transverse reinforcement bars, can be quickly installed and assembled in a standardized manner. High production efficiency and convenient transportation greatly reduce the procurement cost of enclosures.

金属围挡安装方便、快捷、而且非常牢固。能够重复多次使用，不会对城市环境造成影响。使用者还可以在彩钢围挡上做广告位，提升利用空间。

The metal fence installation is convenient, fast, and very sturdy. Can be reused multiple times without affecting the urban environment. Users can also create advertising spaces on the colored steel fence to enhance space utilization.

金属围挡可以抗御各种恶劣气候，不怕风吹日晒雨淋，防尘吸音。并且它本身是一种防火材料，能够有效延缓火势的蔓延，可以保障人身和财产。

The metal enclosure can withstand various harsh weather conditions, and is not afraid of wind, sun, rain, and dust, sound absorption. And it itself is a fireproof material that can effectively delay the spread of fires and ensure personal and property safety.

第二类、PVC围挡：又称市政围挡、工程围挡、工地围挡、塑料围挡、市政围挡、或围栏）

Type 2, PVC enclosure: also known as municipal enclosure, engineering enclosure, construction site enclosure, plastic enclosure, municipal enclosure, or fence

这类围挡主要材料是聚乙烯和钙粉配比而成，PVC围挡标准版（2.5米高、3.0米宽、板厚2.2厘米），影响PVC围挡主要是PVC板面的材质，聚乙烯和钙粉的配比的不同成型后的板面也不同，好的PVC板面有很好的韧性，不易破损发脆、光洁度高、容易清洁、阻燃美观度高。这一类围挡，可使用三年以上。

This type of fence is mainly made of polyethylene and calcium powder in a ratio. The standard version of PVC fence (2.5 meters high, 3.0 meters wide, and 2.2 centimeters thick) mainly affects the price of PVC fence due to the material of the PVC board surface. The different ratios of polyethylene and calcium powder also result in different molded boards. Good PVC boards have good toughness, are not easily damaged or brittle, have high smoothness, are easy to clean, and are flame retardant and aesthetically pleasing. This type of fence can be used for more than three years.

4. The inner cavity of the enclosure is reinforced with galvanized lining steel or aluminum alloy, which has sufficient strength and impact resistance, making the PVC enclosure both steel

材的强度和PVC的美观；

The strength of the material and the aesthetics of PVC;

5.采用特种配方和专用紫外线吸收剂，不褪色、不发黄、不脱皮、不开裂、不起泡。

5. Adopting special formulas and specialized ultraviolet absorbers, it does not fade, turn yellow, peel off, crack, or foam.

第三类、铁皮围挡：别称（彩钢围挡、简易围挡、移动围挡）

Third category, iron fence: alternative name (color steel fence, simple fence, mobile fence)
