Q:Curtain wall works keel wall thickness is the smallest number

Glass curtain wall: Vertical keel: aluminum section of the opening part of the thickness should not be less than 3.0mm, the thickness of the closed part should not be less than 2.5mm; profile hole between the wall and the screw directly when the threaded connection. Its local thickness should not be less than the nominal diameter of the screw; steel section of the main part of the thickness of the thickness should not be less than 3.0mm. The thickness of the main part of the section of the aluminum alloy section shall not be less than 2.0mm when the span of the beam is less than 1.2m. When the span of the beam is more than 1.2m, the section is mainly affected by the force of the cross section. The thickness of the part should not be less than 2.5mm. The thickness of the section should not be less than the nominal diameter of the screw when the thread between the hole and the screw is directly connected with the screw. The thickness of the main section of the steel section shall not be less than 2.5mm. Construction, the steel keel is generally not less than 4mm, because less than 4mm when welding easy to wear.

Q:If it is finished, width and thickness of about how much can be customized according to the size I need?

Under normal circumstances Stretching can be finished, can also be used aluminum mold or aluminum (stainless steel) bending to deal with. Profiles can be customized, if the amount of large, then the mold may also be cheaper, a lot of consultants in the technical requirements mentioned in the expansion joints finished components are more expensive ~ ~ ~ ~ If the gap is large, it is recommended that you still use the plate off it, the size is too large, the mold is also very laborious.

Q:Stainless steel profiles can do curtain wall materials

Stainless steel profiles can not do curtain wall materials, steel aging corrosion can not be solved, the latter part of the maintenance costs will be very high, and now the curtain wall structure is generally made of aluminum alloy.

Q:Will the theoretical weight of aluminum alloy how to calculate? Glass curtain wall above the aluminum.

With the aluminum alloy cross-sectional area multiplied by 2.713 to get the aluminum alloy line weight. That is the theoretical weight. The cross-sectional area can be made directly using CAD. Use the reg command to place the aluminum surface of the drawing, and then use the aa, o command to get the cross-sectional area.

Q:140 type aluminum alloy curtain wall frame how many square

Do not use the cost of cutting costs generally 550 to 700 (quotation 800 ~ 1100), the unit price depends mainly on the separation, glass, labor, and management, because the price of glass is very different. The size of the aluminum lead to the amount of how much. The complexity of the construction leads to the growth of labor prices. Management of good or bad lead to waste of materials, personnel lost work!

Q:110 full hidden series curtain wall dedicated aluminum prices

The price of aluminum and its series does not matter, mainly related to the surface treatment, the aluminum price at the time of purchase and the processing costs of different manufacturers

Q:Can the glass curtain wall frame be made of steel?

Do not recommend the use of steel-plastic material to do the curtain wall, steel itself is not specifically used for the curtain wall of the material for the production side selection , Even with steel to do, but also with the doors and windows of the material instead of PVC itself, the strength of compression and thermal expansion and contraction of the performance are not as good as aluminum, why must use steel materials, steel is the advantage of insulation, noise , Heat insulation, flame retardant. Look carefully

Q:What are the insulation curtain wall aluminum profiles?

Curtain wall insulation profiles are generally used with the curtain wall, there are two kinds of plastic and wear

Q:What materials are required to be tested?

Curtain wall works need to re-inspection materials The first is the keel material: channel, angle, some supervision also requires steel to be measured; followed by chemical anchor to do on-site drawing experiment, as if to do three groups; and then is the glass aluminum. Main profiles (including aluminum and steel profiles), screw bolts, drawing test, four-color inspection, hardware accessories The project is mainly hidden before the board, including steel keel, anti-corrosion operations, materials, such as inspection and other processes.

Q:Specification for aluminum alloy profiles for curtain walls

40 series of profiles which have several specifications
