Generally 100 yuan a square meter

Q:What are the differences between steel doors and windows and aluminum doors and windows? Which is better? Thank you for answering

Aluminum durable endurance, seal is not good, plastic steel cheap and durable, easy to go type,

Q:Steel doors and aluminum alloy door which is good

Both have their own advantages and disadvantages, and corresponding to the different decorative environment should be used the most suitable door, so as to play a more perfect effect: 1, wind pressure strength and watertight performance: As the plastic steel door material strength and rigidity is relatively low, although after processing steel to enhance, but its wind pressure and watertight performance than aluminum level lower one level. According to the end of 1998 OKorder enterprises to submit 425 batches of steel doors three examples of performance analysis seriously pointed out that "plastic doors in high-rise buildings should be used with caution." So, in the high-rise building, we use the most suitable aluminum alloy door. 2, airtight performance: Plastic doors because of the box, fan parts are welded, so the air tightness should be slightly better than the screw of the aluminum alloy door, but the aluminum profile height accuracy, box, fan with more closely, so the two are still in At a level level. ? 3, insulation performance: Aluminum door insulation performance as plastic steel door is good, but the two of the whole heat transfer coefficient ratio is only 1.36 times (single door) and 1.44 times (single frame double glass door).

Q:What is the difference between steel doors and stainless steel doors and windows?

Plastic steel doors: PVC, modified PVC, resin and other major raw materials, according to certain design requirements, in accordance with relevant national standards, in the profile cavity filled with lining steel (lining steel generally 1.5mm galvanized cold Steel), with a special machine for cutting, welding, installation made. Stainless steel: stainless steel acid is short, resistant to air, steam, water and other weak corrosive media or stainless steel with stainless steel known as stainless steel; and chemical resistance to corrosion medium (acid, alkali, salt and other chemical erosion) corrosion The steel is called acid resistant steel.

Q:What are the specific models, and how to define

Plastic doors and windows by way and performance division, mainly in the following series: 1, according to the opening way is divided into: fixed windows, hanging windows, hanging windows, hanging windows, vertical window, flat windows and doors, pulley flat window, pulley window, flat open under the doors and windows, sliding doors and windows, Window, folding door, to the spring door, to enhance the sliding door, push the folding door, inside the sliding door. 2, according to performance is divided into: ordinary doors and windows, sound insulation doors and windows, insulation doors and windows. Plastic doors and windows are made of polyvinyl chloride (UPVC) resin as the main raw material, plus a certain proportion of stabilizers, colorants, etc., by extrusion molding, and then by cutting, welding or screwing made of doors and windows frame fan, Equipped with sealing tape, tops, hardware, etc., at the same time to enhance the rigidity of the profile, more than a certain length of the cavity needs to fill the steel lining (ribs), made of portal windows, called steel doors and windows.

Q:Please answer directly, thank you

Steel and steel door prices to see the size and quality requirements, if there should be identified in the hardware or other stickers or make the spray marked, the material is made of steel profiles and accessories manufacturers, Eurasian is also played a role in assembly

Q:Custom steel doors how much money a square

Custom steel doors made of single-layer steel 140 yuan a square, double-layer steel 160 square. Of course, aluminum is good, no deformation, no yellowing, do not fall off.

Q:Will the new processing plant, associated with the installation, is not the business tax and value-added tax have to pay, is the value-added tax, then the tax burden to achieve how much? Small-scale good, or the general taxpayer good

1, processing with the installation, the main business should be processing tax provisions in full payment of value-added tax 2, for what type of business depends on your business customers, if your customer base for the general satisfied that you apply for the general taxpayers more appropriate, because the input tax can be deducted from the output tax can pay less tax, on the contrary small size Because the small taxpayer tax rate is low, the processing industry is 6%, the general taxpayer tax rate is 17%.

Q:Plastic doors and windows will not produce formaldehyde

Plastic is the main component of PVC-U extrusion molding doors and windows materials, that is, we said the plastic. In the course of processing to the profile to add matching lining steel to prevent deformation of the profile. Plastic steel / steel. So do not produce formaldehyde!

Q:What is the bright and unsharpable steel doors?

A fixed glass that can not be opened, and a fixed part is separated from the door.
