To make a perfect decoration and excellent construction, it is very important to choose a good decoration company, because only choosing a good decoration company can ensure the quality of the whole house's decoration and construction. Then, how can we ensure that we find a family? Satisfying decoration company? 1, inspection decoration company In general, we can first look at the status of the decoration companies, which mainly include their office locations, management and design capabilities, and construction teams. At the same time, they can also look at their offices to see if there are any plans on the progress of the project, the dispatch of the designers, supervisors and foremen. Then check whether the decoration company has the qualification certificate and business license issued by the building authority, whether it has the design and construction capabilities, and then check the registration period and registered capital to determine the scale of the development of the decoration company. Companies with relatively early years of registration are generally time-tested companies, and their capabilities are relatively high. According to the different types of registered capital, the decoration company will have a difference in its company name. In general, the decoration engineering company has the strongest strength. They are generally registered with the Construction Committee; followed by the limited liability company, followed by the design company and the decorating company. ...... You can also request to check the quotation and quantity analysis sheet of a project they are currently constructing to determine the budget transparency of the construction team and whether the entire budget is transparent and reasonable. 2, visit the decoration company's model room After inspecting the decoration company, you can also request to visit the model house of the decoration company, look at several construction sites under construction or projects that have already been completed and will be accepted immediately. If possible, you can also comprehensively inspect and understand the entire construction team at the site. The management level and craftsmanship level, while observing the craftmanship and technical level of the construction personnel at the site, can also consult with other owners on the evaluation of this construction team. 3, view the relevant personnel's qualification certificate At present, the home improvement construction team is relatively confusing. Some people only play short-term workers on construction sites for a period of time. Several people will be drawn to form a construction team to begin the renovation and other engineering teams will work on the project. Later, a few decorators were temporarily picked up. As a result, their technical level was difficult to guarantee and there would be no employment permit. As a result, many problems have arisen in the entire renovation project. For example, because of the lack of technology, the painted paint has been discoloured and peeled off in a short time. In addition, serious water seepage occurred in some projects. In response to this situation, the Ministry of Construction announced the “Architectural and Finishing Engineering Construction and Acceptance Regulations†industry standard and required qualification certification for construction coating companies. At the same time, the construction personnel must also carry out corresponding technical guidance and professional training. Qualification certificates can only be issued after passing the assessment. In view of this, when we determine the construction team, we must check the relevant personnel's qualification certificates. 4, inspection of the decoration company's late service Some people are going through the above-mentioned inspections, they are ready to determine the decoration company, but you still have to do the last thing before the determination - to examine the decoration company's late service. Because in the process of home renovation, the quality of some construction projects was difficult to see at that time, and some projects even left technology dead angles, such as the cracks on the wall after decoration, etc., then good post-service It is very important. Therefore, in determining the decoration company, we must carefully check what their service system is, whether it is perfect, whether it can provide enough good post service...

Although there are many types of tapping screws, they all have the following similarities: Round head Tapping screw,hex tapping screw,flat head tapping screw,pan head tapping screw,truss head tapping screw Shenzhen Lanejoy Technology Co.,LTD , https://www.brassinsert.net
(1) are generally made of carbonized carbon steel (accounting for 99% of total production). It can also be made of stainless steel or non-ferrous metals.
(2) The product must be heat treated. Carbon steel tapping screws must be carbonized and stainless steel tapping screws must be solution hardened. In order to make tapping screws to meet the requirements of the standard of mechanical properties and performance.
(3) The product surface hardness is high, the core toughness is good. That is, "soft inside strong outside". This is a major feature of tapping Screw performance requirements. If the surface hardness is low, it can not be screwed into the matrix; If the core toughness is poor, a twist will break, can not be used. So "inside soft outside steel" is self-tapping screw to meet the use of performance, very important requirements.
(4) The surface of the product needs surface protection treatment, generally electroplating treatment. Some product surface must be treated by phosphate (photostatting), such as wall panel self - tapping screws for photostatting.
(5) Production by cold heading process. It is recommended to use high-speed cold heading machine and high-speed wire rolling machine or high-speed planetary wire rolling machine. High speed is emphasized here to ensure product quality. Only the head of tapping screw produced by high-speed machine is well formed and the thread quality is high.
