1. The structure can be divided into three types: framed, semi-rimless and frameless:
(1) Frame: The metal frame is mainly made of aluminum alloy frame or stainless steel. The plate is made of tempered glass or PS (polystyrene). When purchasing, it is necessary to pay attention to whether the surface is scratched or not. Whether there is close contact, whether there is a plastic or metal cover on the top of the frame, whether the switch is smooth or not, directly affects the waterproof effect of the door and the brake between the fireproof and magnet strip design.
(2) Semi-frameless: The outer frame is made of aluminum alloy frame or stainless steel, and the plate is mainly tempered glass.
(3) Frameless: Mainly composed of hinges, clips, shear rods and tempered glass. Because it is a frameless design, the design of the wall requires a high degree of material and verticality, such as light The compartment or the whole bathroom, if it has a reinforced design at the hinge fixing, can not be installed, otherwise there is a safety hazard.
2. Tempered glass: Most people think that tempered glass is superior to tempered glass, which is a misunderstanding. In the West, the former is referred to as Tenpered Glass or Toughened Glass. Because of its intensity, it is usually 4 to 5 times that of ordinary glass. However, it should be noted that some manufacturers use heat-reinforced glass or semi-tempered glass in order to reduce costs, and their strength is only 1 to 2 times that of ordinary glass, and it is no different from ordinary glass when broken. Can not compare with the former. The glass used for the shower door must meet the safety glass standard, that is, it must be tested through the impact of temperature difference damage before it can be applied. In addition, people generally think that the thicker the glass, the better. In fact, as long as the former can pass the test, the thin glass is beneficial to the service life of the product (the more weight the glass is, the greater the load on the pulley and the hinge) and the safety. In general, a framed glass door uses tempered glass of 3 to 5 mm, and a frameless glass of 6 to 8 mm is sufficient.
3. Surface treatment: The metal surface of the general shower door frame material can be divided into coating (powder or liquid) and electroplating. No matter which process is used, it is necessary to know the coating film thickness, hardness, brightness, adhesion, etc. It is resistant to thick salt spray and chemical test. Because it is installed in the bathroom with high temperature and chemical products are often used, it must not be taken lightly for metal surface treatment.
4. Location of the factory and its after-sales service: If the shower room is a durable endowment from an economic point of view, it must be switched on and off every day. Except for adults and children exerting different strengths and strengths, and due to personal feelings. Inappropriate undulations or improper use practices may not result in the expected useful life. However, the shower door is mainly based on pulleys and hinge switches, plus the plastic and hardware accessories of the combined products. If the manufacturer or its distribution agency can provide professional services for this product, I believe that this group of shower rooms will not become orphans in the bathroom.
5, type and size: Each bathroom size, size is different, so when choosing, the subjective and objective factors need to be considered, in general, open the door can be divided into horizontal pull-style open and inward folding. In addition, unless the shower space is large. Inward folding should be avoided to prevent accidents when someone showers, and the door cannot be opened, resulting in regrettable things.

Non-tapping screws are machine Screw, the pieceworker to be fastened must be tapped with taps in the screw hole in advance to match the screw threads.
The difference between tooth screws and other screws depends on whether they can be used together with nuts. Tooth screws can be used with nuts. And relative to the screws of other teeth, there are self-tapping screws. The nut of this kind of screw has no bow teeth. As for the standard teeth and fine teeth are only different pitch, it is the nut of the machine screw
