有，型材它了很多种不同的类型，首先是材料上来说嘛，我们用的多的就是铝合

Yes, there are many different types of profiles. First of all, in terms of materials, we mostly use aluminum alloy and plastic steel. Now, if the general customer here is concerned about this material, the customer is more cold about aluminum alloy, but for plastic steel. Customers don't catch a cold and think that plastic steel is not good, but from our design point of view, plastic steel is much better than aluminum alloy. There is another, because each profile has a different cross-section and thickness, so the cost of the entire project is different. Another thing is that if we cannot pass the energy-saving calculations, we may choose three-glass and two-hollow glass. At that time, the requirements for the entire section of our profile will be very large. If we choose this profile, the first direction is to look at the customer's acceptance and willingness of aluminum alloy and plastic steel in the local area. This is the first one. The second one is that we will choose which specifications of profiles based on the calculation results of the entire design.

Yes, profile it has many different types, first of all, materials, we use more is aluminum alloy and plastic steel, and then now this side of the general customer he said to this material, customers on aluminum alloy more cold, plastic steel customers do not have a cold, will feel that plastic steel is not good, but from our design point of view plastic steel is much better than aluminum alloy. There is another, because each profile section, thickness is not the same, the cost of the entire project is not the same. There is also a if we can not calculate energy saving, may choose three glass two hollow glass, at that time the entire section of our profile requirements will be very large. If we choose this profile, the first direction is to look at the local customers of aluminum alloy and plastic steel his acceptance and willingness, this is the first. The second is that we will choose which specification of the profile based on the calculation of the entire design.

Yes, there are many different types of profiles. First of all, in terms of materials, we use more aluminum alloy and plastic steel. Now the general customers here are more interested in aluminum alloy than plastic steel. They think plastic steel is not good, but from our design point of view, plastic steel is much better than aluminum alloy. There is another one, because the section and thickness of each profile are different, the cost of the whole project is different. Another is that if we can't pass the energy-saving calculation, we may choose three glass and two hollow glass. At that time, the requirements for the whole section of our profile will be very large. If we choose this profile, the first direction is to see the acceptance and willingness of local customers for aluminum alloy and plastic steel. This is the first one. The second is that we will choose which specification of profile according to the calculation results of the whole design.<br>
