Why choose steel doors and windows

Buying steel doors and windows is easy and easy to say. It's hard to say. What is easy is that as long as they are willing to spend money, they basically go to the building materials supermarket or the high-end building materials city to randomly choose a quality that hasn’t been said. Of course, it is difficult to guarantee that these places will also mix in some unscrupulous traders, and they will put prices in order to win the tourists. The report is very low. We only need to ask if we have a price.

It's hard to find hard-to-find steel that is genuine and affordable. Especially in the mid- to low-grade building materials city, one family is lower than one offer, and every family shoots their chests and says that their homes are real goods, or revealing the vulgarity of other businesses. At this place, consumers will have to keep their eyes open. Too cheap is certainly a problem, expensive is not necessarily good, the contract must be signed rigorously, the profile, steel lining, glass, hardware, other accessories brand, model, processing technology, installation process, implementation standards, etc. Write clearly, the things promised by the business must fall on paper.

What I have chosen this time is a very good German high-end window with a large reputation, and it feels general. I will try to speak objectively about my satisfaction with Degussa and my lack of satisfaction. I hope to promote the advantages of Dego Energy and improve the deficiencies.

Satisfactory place:

1. Quality of profiles and glass

Although the 800 telephones printed on the profiles have been unanswered and cannot be authenticated by telephone, they can be judged as genuine by looking at colors, coding, and seals. The glass is smooth and translucent, and the insulating glass is sealed tightly. It is transported up the elevator. When neighbors in the building saw people praise.

2 cost performance

The price is cheaper than supermarkets and high-grade building materials cities. It is more expensive than the middle and low-grade building materials city, but the quality can be guaranteed basically, so the price is good and it is not worry.

3. Installation of doors and windows

The installation of the master craftsmanship is good, and the two little workers are also very diligent in their work. Basically, all the doors and windows have passed the acceptance of the horizontal ruler, and they are very regular in terms of buckling and sealing, and they are quite satisfactory in terms of overall effect.

Unsatisfactory place:

1. The thickness of steel liner is not clear

Degussa guarantees the use of steel liners with a thickness of 1.2 mm, but later verbally told me that their steel liner thickness is between 1.0 and 1.1, which makes me doubtful.

2. Some of the unspoken rules are not stated explicitly in the quotation, but only later.

For example, some fixed windows cannot be fixed at a fixed window price; glues need to be charged; measured according to the size of the outer mouth and without deducting the strength column size; the following 6 square meters are not connected; the dismantling of the old window is subcontracted, so it needs to be 10 square meters. More workers come to...

3. Installation time

Measured on April 12th, it was originally scheduled to be installed after 1 week. Since it was not processed, it was installed on the 24th and was installed on the 26th because glass was not in place. I found someone to remove the original window on the 23rd. Fortunately, it did not rain in the middle of the day.

1. A single window is less than 1 square meter counted as 1 square meter.

2. Individual doors are less than 1.5 (some merchants are 2 square meters) and count as 1.5 (2) square meters.

These two, I think there is a certain reason, because the smaller the window, the relative use of profiles and steel, the greater the proportion, the smaller the proportion of glass; the larger the window, the larger the glass area; and glass Steel profiles and steel linings are cheap, so businesses will have such regulations. However, if the window is a minimum of 1 square meter, the calculation of the minimum 1.5 square meters of the door is relatively reasonable, and some businesses in the form of a contract stipulate that the minimum of 2 square meters of the door is to compare the chicken thief.

3. The size of the L-shaped window is calculated according to the outer mouth, and the size of the reinforcement column at the inflection point is not reduced, although the reinforcement column is for single payment.

This is obviously irrational because I don't need to say it. Everyone knows by themselves.
