Tips for purchasing frameless balcony

National standard description

The industry has developed in China for nearly 10 years, and there is no national standard for the time being. Due to the low industry threshold, the development of various manufacturers is uneven, and the market price ranges from 100 to more than 700 per square meter. Many irresponsible manufacturers have also brought many negative effects to this industry.

Manufacturer scale certification

The scale and relevant qualifications of the manufacturer can guarantee your after-sales service. Large manufacturers are superior to small manufacturers in terms of experience, personnel, technology, equipment, and the support force constrained by users' word of mouth; Moreover, it is easier for large manufacturers to obtain better products from material suppliers.

Aluminum and composition list

The thicker the aluminum material, the better. The stress part is greater than or equal to 3mm, which is enough to withstand the height of 2.3 meters in coastal cities. The key is aluminum, without impurities. What aluminum-magnesium alloy and titanium-magnesium alloy are advertising words, and the national standard components of aluminum alloys contain different contents of trace elements. As long as the manufacturers don't mix recycled aluminum with waste aluminum, it's good enough. The difficulty is that many small manufacturers blindly reduce costs and deceive users with recycled aluminum in order to meet the low-cost needs of customers. On the premise of ensuring quality, the cost has a bottom line. So it's best not to pursue products that are too cheap.

Waste aluminum has the following characteristics:

A. the section is dark and uneven;

B. For a five-centimeter-long material segment, it is not easy to open, but it will not rebound after opening; Because pure aluminum is elastic and soft.

C. When general manufacturers use recycled aluminum, a thick coating is sprayed on the surface of the profile to cover the inside.

tempered glass

Tempered glass must be completely tempered. The standard manufacturer's inspection method is that the steel ball of 1kg is suspended at the height of 1 m, and the center of tempered glass is impacted by free fall, and it is qualified if it is not broken. Therefore, the most operable inspection method for users is to put a pad at both ends and stand an adult in the middle, which can undergo complete tempering.

What needs to be reminded here is that tempered glass is characterized by strong plane stress, but the edges and corners are very fragile, and they are often broken when touched. Another feature is that the fragments are angular and granular and will not be sliced. All-tempered tempered glass will also explode itself, but the probability is very small.

Core stress component

Many users only care about aluminum and tend to ignore hardware. Wheelset is the core stress component in frameless balcony window, and the quality of wheelset is directly related to the push feeling and service life of frameless balcony window. Smart wheels are made of bearing steel, which is not easy to rust and shake; The shaft connecting the wheel and the glass clip profile is also very important. Generally, high-strength metal is used, and the overall L-shaped structure is stronger. Most of the frameless balcony shafts in the market are extruded from waste zinc alloy powder, which is very fragile. Therefore, each glass of frameless windows in China is usually less than 500, and the shaft made of stainless steel 304 has strong bearing capacity, and the width of a single glass can reach 600-700.

Detail processing

Details are the best way to find defects. Many cottage products are generally difficult to see flaws in appearance, and the details are always far-fetched. Here are some common examples of rough details.

A. It is obvious that a certain ingredient is forcibly added, which is uncoordinated and incomplete;

B. the surface coating of the profile is easy to fall off;

C. The profiles on the same window have obvious color difference;

D. Shake the sash by hand, which is easy to shake in the direction perpendicular to the glass;

E. The plastic parts are not thin and have many obvious burrs;

F the shaft is made of waste zinc alloy, which has many bubbles and is easy to break;

G. When the sash is fully opened, the aluminum color is naturally exposed at the process opening part and the end face of the glass clip profile, and the decorative parts are not covered;

H. Single window sash is easy to topple during opening;

First, the whole window is exposed, and there are core-pulling rivets for links everywhere;

J connect the glass and the glass clip profile with aluminum core-pulling rivets, and the core of the core-pulling rivets is left in the rivets.

These are obviously rude treatments. In short, shop around and you can find problems by comparison. Every manufacturer is Wang Po, and can only say that his melons are sweet. Look at a few more and you will know more.
