Metal roofing. Suggestions on the selection of metal roofing materials for the top of the curtain:
Steel plates cannot be selected; The service life is as little as three or five years, and more than ten years. The service life is not reached.
The cost of titanium alloy plate is about 3,000 yuan per square meter. Coupled with construction profits, taxes, warranty losses, etc., it is expensive!
Aluminum-magnesium-manganese alloy plate can be used, aluminum-magnesium-manganese, the color is adjustable, but there is no metallic texture of titanium-zinc plate. (The material price is 100-200, and the construction contract price is about 400-600 yuan square meters).
Hope it helps!

Anonymous users2024-02-06Henan Xiangyizhu answers for you: what material is good for metal roofing? Next, I will send a few metal roof comparison tables of various materials, you can choose the materials you need according to the project's own situation!
Comparison of the main materials of various metal roofing systems.
The main specifications of various metal roofing panels.
Comparison of the basic functionality of various metal roofing systems.
Recommendations for the selection of various metal roofing systems.
Combined with the above analysis, when choosing a metal roofing system suitable for the building, it is not only necessary to consider the design period, local climatic conditions, and the performance of the system, but also related to the requirements of the building itself in terms of modeling and appearance effect. In fact, in real engineering, the appearance of metal roofing systems often dominates. Therefore, when the construction unit proposes or designs the roof scheme, it first needs to understand the specific requirements of the architect or the owner for the appearance of the building, and then consider the specific performance of the building.
Under normal circumstances, the building body with low requirements for appearance can choose to wear nails or concealed metal roofs, but the nails are best used in zero-hour buildings or buildings with low requirements for waterproofing, so that later maintenance and replacement will not affect the normal use. For public buildings with high appearance requirements, large area or span, and long service life, it is best to choose an upright seam or occlusal edge metal roofing system. Among them, if the appearance of the building roof needs to present different materials, such as:
Stone, metal sheets of various shapes, glazed glass, etc., i.e., when a double roof form is required, the vertical seam metal roofing system is the most preferred. When the metal roofing panel is directly used as a surface layer or the volume is small and the shape is complex, and the appearance requirements are relatively high, the metal roofing system with vertical occlusal edge is preferred. The application of the flat lock roofing system is generally directly requested by the architect or owner, but it should be noted that it must be attached to the waterproof system of the inner layer, and the use area should not be too large, and the specifications of the plate itself are relatively small.

Anonymous users2024-02-05Introduction: Metal roofing simply refers to the use of metal plates as the cover of buildings, this phenomenon is very common in our lives, especially in some large-scale factories and warehouses, the application of metal roofing is very common, so, what does metal roofing refer to? What are the materials that can be used as metal roofing?
Introduction to metal roofing
Metal roofing refers to a material made of sheet metal that is used as the roof of a building. The part of the building that uses metal roofing usually looks like it is paved with a layer of metal material, but in fact, the material made of metal roofing is not only metal material, but also in terms of basic metal materials, in order to be used to make metal roofing, it must also meet certain standards, and it is by no means ordinary metal can be made into metal roofing.
Metal roofing generally includes two parts: metal plate and coating, among them, there are many types of metal plates, mainly veneer and composite board, composite plate plate is between two metal plates to add a layer of insulation layer, the role in actual use is more prominent. Metal roofing can be assembled before construction according to the construction requirements, or directly assembled at the construction site, the types and forms of metal roofing are very rich, therefore, its application range is very wide, as large as factory buildings, small to their own housing, metal roofing can come in handy, but it should be noted here that the applicable waterproof level of metal roofing is 1-3 levels, in practical application, we should abide by this specification.
What are the metal roofing materials?
Metal roofing needs to have good leakage, snow and water resistance, so the materials used to make metal roofing should be particularly particular. First of all, in the selection of metal plate materials, both the material is required to have a higher plate rib, and the thickness is required to be between millimeters, however, there are still many materials that can be used as metal plates, in addition to the most common steel, aluminum alloy, zinc plate, copper plate, stainless steel plate, aluminum-magnesium alloy plate and titanium alloy plate can be used as metal roofing metal plates, we can choose according to the actual application environment.
Secondly, the selection of coating materials is also very strict, most of the foreign imported paint as the surface layer of the metal roof, among them, the coating materials applicable to different materials of metal plates are also different, for example, the aluminum-magnesium-manganese alloy plate can be imported from the United States and Australia for the construction of special paint, the life of this paint can reach 15-20 years, can effectively protect the metal plate, the ordinary alloy plate can be selected from the general roofing paint in Europe and the United States.

Anonymous users2024-02-041. Foam concrete. Foam concrete is a common roofing material, which has good thermal insulation and good thermal insulation effect. Secondly, its sound insulation and fire performance are very good, easy to construct, safe and environmentally friendly.
2. Foam glass insulation board. Foam glass insulation board has the characteristics of light weight, small water absorption, non-combustion, non-toxic, etc., and is widely used in petroleum, chemical, underground engineering and other industries. At the same time, it also has the functions of heat insulation, heat preservation and sound absorption, so it is often used in civil roofing materials, which have stable chemical properties, easy processing and no deformation, and are durable.
3. Rock wool, mineral wool and their products. This kind of roofing material is mainly made of slag and other natural ores as the main raw materials, which are melted into fibers at high temperature and processed by adding an appropriate amount of binder. It is characterized by low thermal conductivity, fireproof and non-combustible, convenient construction, and high cost performance.
4. Phenolic resin insulation board. Phenolic Mengzi resin insulation board is mainly made of phenolic foam as raw material, made of thermosetting phenolic resin foam, which has the advantages of fire prevention, non-combustion, no Huling poison, etc., and is an ideal thermal insulation material in HVAC and refrigeration engineering.

Anonymous users2024-02-03In addition to the cost, climate, region, building function, environmental protection and many other reasons, the structure of the building is an important factor.
Suitable for the use of paint waterproof parts: wet base layer, poor drainage or perennial water, uneven base and many prominent embedded base layers, back water surface waterproofing, water tank waterproof, perennial typhoon level and more areas, etc., among which the wet base layer, poor drainage or perennial water.
The base layer is suitable for membrane waterproofing: the bottom layer of the wooden structure slope tile house is waterproof, etc.
In the case of the metal factory house, to put it simply, it depends on whether the roof is flat, if the roof is not flat, it is not suitable for membrane waterproofing, and the roof temperature is high to use elastic coatings, it is not recommended to use membrane waterproofing, and the metal roofing membrane waterproofing should be used as a protective layer, and the roof bearing problem should be taken into account. The coating is waterproof and does not do the protective layer, and the aging performance is better than that of the membrane, and it is easier to repair than the membrane if there is a problem.
In short, the most suitable waterproofing material should be selected according to the specific situation of the base layer.
Hope it helps!

Anonymous users2024-02-02Hello: The waterproof materials that can generally be used for metal roofing are: acrylic waterproof coating, special waterproof coating for metal roofing, TPO waterproof membrane, etc.
However, the specific problems still need to be analyzed on a case-by-case basis.
At present, there are many waterproof coatings for metal roofing waterproofing, and special waterproof coatings for metal roofs are generally used (cost-effective). If there are thermal insulation requirements or high standard requirements of medical electronics, the factory uses TPO waterproof system (high cost.
The service life is more than 10 years.

I'm also worried about this problem, I have been resigning for more than a month, and I also want to start my own business, but there is no suitable project at present, and the money is not very much, so I finally found one, do **** business, the investment is only more than 10,000 yuan, you can open a store or not, I was going to do it first, and if you think you can in the later stage, you can get a storefront, I learned about the situation in our local area, and I feel that this business is indeed an unpopular business, and there are very few people who do it, but I really don't know how to do it. So I searched on the Internet and found the Yixing home company, they are specialized in **jewelry** project, do very formal, and now they are also recruiting students, teach you to identify the true and false technology, and then receive all the goods package**, I feel that this business is risk-free, I learned a skill, I received **, not something else, **is money, no risk, all very excited to run to their company, but the result did not make me angry, someone in our county has done it, but my wife has just given birth to a child, I can't go to other places, and I want to come back to develop from working outside. It's a really good business. So now I'm still thinking about whether to go to the county next to me to do it, and I really don't want to work anymore.
