Small common sense of home improvement hardware that can't be ignored

Core Tip: Hardware costs about 3%-5% of home improvement costs. Although the proportion of expenses is small, the whole house decoration is almost inseparable from it. In fact, too professional procurement can be left to the decoration master to prepare. But sometimes, some products are mixed, and indeed many consumers are very "scratching their heads."

â—†Hardware accessories mainly look at materials and workmanship

According to Xingke Hardware Network, the general hardware accessories are mainly composed of copper, alloy, stainless steel and iron, and their prices are also very different. At present, the most used home decoration is stainless steel hardware, but the stainless steel material has the disadvantages of impure material and easy to print water stains. At present, many families have begun to use aluminum alloy fittings. According to industry sources, the aluminum materials claimed by some merchants in the market are actually only alloy materials containing aluminum, which are blended with other components such as silicon and magnesium, different aluminum alloy materials and surface film thickness and surface treatment process. There is a big relationship, these factors often affect the price and quality of materials. The CEO of a certain company introduced that the surface treatment process mainly includes oxidation, sanding, electroplating, wood grain and baking varnish. The price of the products is also very different. Taking the sliding door frame as an example, the average market price of products using oxidized matting process is in each square. The meter is about 180 yuan, and the electroplating process has reached 260 yuan per square meter, and the price difference is nearly 45%.

The common aluminum alloy materials on the market mainly include aluminum-magnesium alloy and aluminum oxide. The price difference between the two is also nearly one-third. Since the surface of alumina and aluminum-magnesium alloy materials looks similar, it is more difficult for consumers to distinguish. Large, but consumers can judge from the aspects of hand and water stains. Experts said that the aluminum-magnesium alloy material is relatively heavy, the surface is relatively smooth, it is not easy to appear water stains, and the toughness is good; while the alumina material has a rough surface, easy to blacken and water stains. At the same time, if there is a slight scratch on the surface of both, the aluminum-magnesium alloy material is easily erased, and the alumina is difficult to remove. In addition, the door handles are also very different in price due to the difference in hole pitch and type.

â—† Beware of stainless steel becoming "rust iron"

Many merchants use stainless steel instead of stainless steel hardware accessories, that is, a lot of iron components are blended in the stainless steel material, and the price difference is nearly twice. Take the towel rack as an example. The price of stainless steel is about 200 yuan per piece. The price of stainless steel is only 70 yuan per piece. The surface is basically the same, but the surface of stainless steel is brighter. The time of using stainless steel is one. Long, the surface is easy to black and rust.

In addition, some counterfeit products use inferior aluminum alloy as raw material, the surface is coated with a layer of metallic light, posing as high-grade stainless steel. Judging these two materials, consumers can tap the surface. If the crisp sound is emitted, it is mostly stainless steel. The dull sound is likely to be an aluminum alloy that is "clothed".

â—†The bathroom is best with silver mirror

According to reports, the mirrors commonly used in home decoration are mainly divided into two kinds of mirrors and silver mirrors. The price difference between the two is about 30%, and the market price of silver mirror is about 80 yuan to 90 yuan per square meter. The square meter is 50 yuan, and the quality is also very different. The difference in materials is the main factor that causes the price difference between the two. The back of the silver mirror is first coated with a layer of mercury and then painted; while the back of the mirror is coated with a layer of aluminum and painted, the effect of waterproofing and anti-fog is reduced a lot. After the water is encountered, the frame of the mirror is easily reddish and the paint surface is easy to fall off. In addition, processing techniques such as baking, printing, and tempering also affect the price of the mirror.

â—†Waterproof coating main agent ratio affects the overall quality

The biggest factor affecting the quality of waterproof engineering is waterproof coating. According to reports, waterproof coatings are mainly divided into water-based and polyurethane. At present, water-based waterproof coatings are widely used in home decoration. There are four main types of waterproof coatings: waterproofing agent directly added to cement, waterproof coating without main agent, and main agent. The rigid waterproof coating film and the flexible coating film with the main agent added. The first type of waterproofing agent is added to the cement, which does not have a waterproof effect at all, and is more common in civil engineering. The most common ones are rigid and flexible coatings, and the difference is the ratio of the main agent to the powder. The ratio of the main agent to the powder of the rigid coating is 1:8, and the flexibility ratio is 1:2. The greater the dose, the better the waterproofing effect.
