Black profile extrusion method:

在型材配方中参与色母料，经过挤出机直接挤出玄色型材，优点是在原挤出机上挤出成品，本钱较低；缺点是型材的耐候性差，很难满足室内的装潢成果的申请。

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:

操作加热和机械覆膜的方法，经过压合将一层玄色膜和粘结胶粘结在绿化护栏的表面。生产制造过程中需要在流水线前途中，品质较好的膜和粘结胶选用进口制造品，本钱较高；施工时玄色膜碰伤时不好修补。

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.

表面喷涂法：

Surface spraying method:

精选色的涂料均匀的喷涂在绿化护栏的可以看见的表面上，可以单面的喷涂，也可以双面的喷涂，色彩多样，生产制造灵活方便。

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.

复合共挤法：

Composite co-extrusion method:

主要是由绿化护栏和一层附加的玄色物料共同挤出构成的型材，生产制造型材使用一种复合模具，生产制造的唱功是往日两个一致六道的型材物料和玄色物料，在离开模具之前汇流到共同挤出成型。

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.
