When it comes to the purchase of hardware products, most of the projects are about to come to an end. The building materials market and large and small building materials supermarkets in Beijing’s four cities and eight districts are also basically in mind. But buying hardware and buying other building materials and furniture can be quite different in the market and in supermarkets. What is the difference between the cats in the hardware market and other building materials consumption? How do you buy them? The reporter went to the major building materials market to investigate and interviewed relevant experts. Experts remind consumers: buy hardware, do not care, at least have to professional.
Faucet: seal difference buy
According to Wang Gong of the Hardware Product Quality Testing Center, many manufacturers are currently pursuing profits, reducing costs, reducing the material of the products, using the eliminated cast iron, rust, zinc alloy, and non-corrosion as raw materials for faucet production. There is a problem with the quality of the product. These faucets with internal materials are difficult to distinguish in appearance. It is understood that the quality of the faucet and the hose is not good, and the problems such as the material and the wall thickness cause the strength performance and the sealing performance of the faucet to fall short of the standard. This situation {TodayHot} should attract the attention of the user.
Wang Gong pointed out that the faucet currently sold on the market has a complicated processing technology and a good surface sealing property. When the consumer is in the process of purchasing, he can see whether there is a gap between the faucet and the switch when turning the handle of the faucet. The faucet with no gaps, easy and unobstructed, and no slippery is better. Inferior gaps are large, and the resistance is large; in addition, look at the faucet parts, especially the main parts are tightly assembled, the valve body and handle of the good faucet are all made of brass, the weight is heavy, and there is a sense of dignity; Identification marks are indispensable when purchasing. Generally, regular products have the manufacturer's brand identity, while some informal products or some quality products often only have some paper labels, or even no marks.
In addition, the most critical quality of the faucet is the valve core. The faucets currently on the market have rubber spools, ball spools and stainless steel spools. The stainless steel valve core is a new generation of valve core material with good sealing performance, stable physical properties and long service life. The main body of the faucet is made of bronze. The good faucet should be cast in one piece. The sound is dull when knocked. If the sound is very brittle, it is made of stainless steel and the quality is worse. The surface of the faucet is galvanized, titanium coated, painted, and the like. The plating thickness is good, and the surface of the plating layer can be observed to be bright. The coating of the imported faucet is thick and not easy to fall off and oxidize. The plating layer should have a protective film, and the plating layer without the protective film is easily faded.
It is still difficult to distinguish the root cause of faucet breakage. At present, the National Technical Quality Supervision Bureau has issued the recommended standards for sealing nozzles and hose standards. These two standards have relatively well defined the quality standards for faucets and hoses. Consumers can go to the quality inspection department to detect the twisting force of the faucet hose, the sealing of the faucet valve core, and the strength of the faucet material, and as a strong evidence of prosecution.
Hardware: a similar price difference
Small hardware refers to furniture hardware, door locks, stainless steel zippers, etc. They {HotTag} account for a small proportion of the cost of the entire renovation process, so many consumers are easy to ignore the quality of the hardware and only consider its price, in fact, hardware is a common part of the home, its quality is related to home improvement design The life of the quality used. The biggest difficulty in buying small hardware in the market is to identify the advantages and disadvantages. Now the manufacturers are basically in the stage of imitating each other in terms of style and technology. Therefore, many booths have been turned, and most of the hardware seen may be similar in appearance. The staff said that it is copper chrome plating, high smoothness and durability, but the price is very different. In a building materials market near Yuquanying, the reporter saw that the price of the triangular basket with similar appearance is from 10 to 30 yuan. The price of the door lock is almost 10 times worse than 30 to 300 yuan.
It is understood that the internal materials of the hardware are mainly zinc alloy, copper, stainless steel, plastic, etc. The best way to distinguish them is to look at their weight. In general, according to the weight, the order of the hardware materials is copper and stainless steel. , zinc alloy, plastic. Due to the different cost of various materials, copper is generally the most expensive among the four materials, followed by stainless steel, zinc alloy and plastic. In addition, the finish of the hardware can also provide us with some purchase information. Compared with the chrome-plated and electroplated surface, the former is brighter and less rusting.
Aluminum gusset: alert to install a scam
Compared with other hardware products, the purchase of aluminum gussets involves the installation and installation costs of the manufacturer. In order to achieve the purpose of attracting consumers to purchase, some building materials dealers tempted consumers to place orders with low installation costs. Generally, the installation cost of light steel keel is about 40 yuan per square meter, and the decoration company's quotation is more than 50 yuan. If someone quotes you a price of 15 yuan per square meter, it is rough in construction and the day is finished. Live, he ended the battle in two hours; maybe he blackened you elsewhere, such as stealing a column and giving you fakes.
According to reports, the cost of the ceiling consists of three parts: the first is the money of the aluminum gusset; the second is the material money of the corner, the general dealer will help you calculate how many corners you need according to your situation; the third part It is artificial money. It should include all excipients, such as the installation fee of 15 yuan per square meter mentioned above. Some are a kind of behavior that deceives consumers. They say it is 15 yuan. It is actually a labor fee and does not contain any excipients. When you install your home, you have to go out and buy keels, nails, etc., and finally calculate the money you spent on the accessories, the freight and the time and energy you took, I am afraid more than 30 yuan.
In addition, there is a misunderstanding in the purchase of aluminum gussets - the thicker the plate, the better. It is understood that some of the miscellaneous uses of cans of aluminum, this aluminum itself can not be made very thin, therefore, in addition to pay attention to the surface finish of the aluminum gusset, but also to observe whether the thickness of the board is even, pinch by hand Think about the board, whether the elasticity and toughness are good.
Where to buy hardware is more cost-effective
In the large home market or supermarket to buy lamps, wires, water pipes, water and other materials in order to protect the safety of the home, even if you spend more money, in order to rest assured. Compared with the same brand in the large and small building materials market, buying ceramic tiles, sanitary wares, and faucets in small markets is more economical while ensuring quality.
The reporter visited the building materials supermarket and building materials market. After investigating the three hardware products of faucet, hardware and aluminum buckle board, it was found that the hardware is the most concentrated, and the goods are relatively complete, mainly the supermarket and the low-end building materials market. Supermarkets from faucets, hardware, aluminum gussets and brand types are the most complete, good service, if you feel unsuitable after purchase, as long as the packaging is intact, can be returned within the specified time, and the products are not only small styles, especially small hardware. And very novel personality, the highest price; low-end building materials market, a variety of hardware, but the brand fish eye mixed, although the price is not high after bargaining, but after the sale is difficult to get protection, it is difficult to return.
According to such market conditions, consumers who need to satisfy the decoration effect to a large extent can save time by purchasing in a large home improvement supermarket; while the figure is affordable, the medium and low building materials market with complete hardware products is selected. Compare and analyze these time, carefully decide, you can spend less and buy good things.
Tips
Fragmented hardware purchase has a coup
1. hinges, guides, hinges
The main types of hinge-type hardware are door hinges, drawer guides and cabinet hinges. The door hinge material is copper and stainless steel. The standard area of ​​single-piece hinge is 10cm×3cm and 10cm×4cm, the diameter of the middle shaft is between 1.1cm and 1.3cm, and the wall thickness of the hinge is 2.5mm to 3mm. When the hinge is selected, it is easy to open without noise. It is preferable to include a ball bearing in the shaft of the page.
The drawer guide rail is divided into two kinds of rails and three rails. When selecting the brightness of the exterior paint and plating, the gap and strength of the load wheel determine the flexibility and noise of the drawer opening and closing. The load-bearing wheel with uniform wear and rotation should be selected. .
The door hinges are divided into two types: detachable and non-detachable. The cover is divided into three types: large bend, medium bend and straight bend. In addition to the visual inspection and the smoothness of the hinge surface of the hand hinge, attention should be paid to the reset performance of the hinge spring. The hinge can be opened at 95 degrees, and the hinges are pressed hard by both sides to observe that the support spring piece is not deformed or broken, and is very strong. For quality qualified products.
2. Handle, handle, lock
Handle materials are zinc alloy, copper, aluminum, stainless steel, plastic, logs, ceramics, etc. In order to match the various styles of furniture, the shape and color of the handle are varied and colorful. The handles of electroplating and electrostatic painting have wear-resisting and anti-corrosion effects. In addition to matching with the decoration style of the room, they should also be able to withstand large pulling forces. Generally, the handles should be able to withstand more than 6 kg of pulling force.
With the gradual fading of the ball lock, the three-in-one handle lock of the switch, the decoration and the handle becomes a fashion lock in the home decoration. According to the material, the handle lock can be divided into space aluminum, stainless steel, copper die-casting, zinc alloy, space aluminum, stainless steel material advanced, after surface treatment, the gloss is bright, the hand feels soft, although it is not easy to fade after sweat and moisture corrosion. Rusty. The die-casting copper handle lock is thicker and the price is moderate, while some of the inferior zinc alloy handle locks are easier to break when used. Because the zinc alloy handle lock surface is copper-plated, it is not easy to distinguish from the copper die-cast handle lock when purchased. The sickle is smashed in the bottom of the two handle locks. The brass color is a copper die-cast handle lock, and the silver-white one is a zinc alloy handle lock.
3. Pendant, basket, shelf
Stainless steel pendants and baskets are mainly distributed in the kitchen and bathroom. The kitchen is widely used in stainless steel baskets, multi-layer racks, seasoning racks, etc. In this type of basket, the frame is made of steel or iron wire and welded. According to the dealers, the main manufacturers of stainless steel pendants and baskets are Zhejiang and Guangdong. The raw materials for the production of Zhejiang enterprises are made of stainless steel, the steel wire is fine, and the plating surface is not smooth enough. The base wire of Guangdong enterprises is thicker, but the welding electroplating process is more advanced. Consumers should consider the bearing weight for selection when purchasing.
All kinds of towel racks and washing racks of the bathroom are made of copper tube welded chrome plating, and the thickness of the tube wall is preferably 1.0mm-1.2mm. Since the bathroom is damp, the flatness of the shelf should be noted when selecting, and the solder joint should be firm and smooth.
