Teach you three ways to order high-quality cast aluminum doors

Step one: Look at the material and details of the product. No matter what kind of door, the most important thing is to be strong and durable, and the stability mainly depends on the material of the door. Cast aluminum doors are heavy. Generally speaking, a door leaf weighs about 150 kilograms. Without a strong steel frame, it would be difficult to support the entire gate. Yilande

At present, there are hot-dip galvanized steel plates, cold-rolled steel plates, cold-rolled steel plates, stainless steel plates, aluminum profiles, etc. Among them, the best material is hot-dip galvanized steel plates. Zinc steel plate (also known as SECC steel plate ), has good hardness and strength, never rusts, and has strong paint adhesion; cold-dip galvanized steel plates and cold-rolled plates themselves will rust; stainless steel plates have poor paint adhesion, and aluminum profiles have insufficient hardness and strength and are prone to sagging and deformation. Poor corrosion resistance. Generally speaking, the thinnest part of the cast aluminum plate on the door surface should not be less than 8mm, so there will be no problem in resistance performance.

Ilande always adheres to the manufacturing concept that every door is a work of art. In \”continuous innovation and pursuit of excellence\” and \”leading, Under the guidance of the product policy of \”high-end and unique\”, based on new technologies, new materials and new processes, we have formulated the research policy of \”excellent original and perfect interpretation\”. Continuous process innovation enables us to improve product quality in a timely manner to ensure competitiveness. . Continue to explore and lead luxury cast aluminum villa doors and provide users with higher quality products.

However, the key to the quality of cast aluminum plates lies in their structural composition. You can see if there are any black spots on the exposed aluminum plate through the keyhole. If this is the case, it means there are a lot of impurities. It is definitely not standard alloy aluminum ingot processing or recycled aluminum mixing processing. The steel plate itself will quickly become oxidized and corroded. Then check whether the welded joints and connection points of the product are smooth and without traces; when the door is closed, whether the lines left on the edge of the door are smooth and consistent, and whether the gaps are large; whether the paint on the surface is even and whether it feels good. You can also scratch the surface with your fingernails to test. Its smoothness and hardness etc. In these details, we can understand the advantages and disadvantages of the product.

The second trick: look at the hardware accessories. The hardware accessories of cast aluminum doors mainly include hinges, locks and sealing strips. Except for the lock which can be selected by the customer, the other two are prepared by the manufacturer. Due to the heavy weight of cast aluminum doors, the quality of the hinges directly affects the function and service life of the doors.

The best hinge currently on the market is the \”three-dimensional dimming hinge\” developed and manufactured by Zhejiang Dingli Industrial Co., Ltd., which has obtained a national patent. The bearing capacity of the hinge alone is more than 800kg, and it has super stability, sealing and safety, ensuring the safety of the gate. Its single-sided adjustable hinge is imported from abroad and has poor anti-theft performance. The other is the \”Heaven and Earth Hinge\” (two sets of upper and lower hinges). The stress point is mainly at the lower part of the hinge. Due to uneven stress points, the wear is inconsistent, which can easily cause the door to sag and deform, affecting the service life.

The sealing strip plays an important role in the sound insulation, insulation and safety of the gate. Currently, the bestThe seal is ethylene propylene diene monomer (EPDM), the same material used on cars. The sealing strip is soft, delicate, elastic and has a long service life. If it is rough, rough and has a poor feel, the sealing strip will be easily deformed, have poor elasticity and crack, which will greatly affect its sealing performance and safety.

The third step: look at the service system. Buying a product means buying a service. A mature manufacturer must have a complete service system. This kind of service is not only reflected in the professionalism of the sales process, but more importantly, in the improvement of the product\’s own structure.

First, let’s see if the product has its own ID card (number) engraved on important components such as cars. If so, that means the manufacturer is responsible.

Second, check whether the product has a warranty card, certificate of quality, and installation instructions (although this is the most important requirement for the product). Basic requirement, but for some manufacturers, this is not necessary).

Third, look at the manufacturer’s warranty commitment. If it is a famous brand manufacturer, it has a shelf life. Of course, the longer the better.
