Black profile extrusion method:

在型材配方中參與色母料，經過擠出機直接擠出玄色型材，優點是在原擠出機上擠出成品，本錢較低；缺點是型材的耐候性差，很難滿足室內的裝潢成果的申請。

Participating in the color masterbatch in the profile formula and directly extruding the black profile through the extruder has the advantage of extruding the finished product on the original extruder with low cost; The disadvantage is that the weatherability of the profile is poor, and it is difficult to meet the application of interior decoration results.

覆膜法：

Film coating method:

操作加熱和機械覆膜的方法，經過壓合將一層玄色膜和粘結膠粘結在綠化護欄的表面。生產制造過程中需要在流水線前途中，品質較好的膜和粘結膠選用進口制造品，本錢較高；施工時玄色膜碰傷時不好修補。

A layer of black film and adhesive are bonded to the surface of the green guardrail by pressing the method of heating and mechanical film covering. In the process of production and manufacturing, it is necessary to select imported products for high-quality film and adhesive in the future of the assembly line, with high cost; It is difficult to repair the black film when it is bruised during construction.

表面噴涂法：

Surface spraying method:

精選色的涂料均勻的噴涂在綠化護欄的可以看見的表面上，可以單面的噴涂，也可以雙面的噴涂，色彩多樣，生產制造靈活方便。

The paint of selected colors is evenly sprayed on the visible surface of the green guardrail, which can be sprayed on one side or both sides, with various colors and flexible and convenient production.

復合共擠法：

Composite co-extrusion method:

主要是由綠化護欄和一層附加的玄色物料共同擠出構成的型材，生產制造型材使用一種復合模具，生產制造的唱功是往日兩個一致六道的型材物料和玄色物料，在離開模具之前匯流到共同擠出成型。

The profile is mainly composed of green guardrails and an additional layer of black materials, which are extruded together. The profile is produced using a composite mold. The singing skill of the production and manufacturing is that two consistent six-channel profile materials and black materials flow into the common extrusion before leaving the mold.
