Reading this article as following please, then you will find why people choose expanded metal mesh for building material. But before that, please allowed me to introduce ourselves first. We are Anping County Dongjie Wiremesh Products Co., Ltd, specialized in expanded metal mesh over 22 years’ experience. We are a specialized manufacturer integrated of research, production and installation, which is rare in the expanded metal market. And Dongjie posses the ability to provide customized solutions for clients.

As a producer and solution provider, we are glad to share with you the reasons why people choose expanded metal mesh as building material.

1. What is Expanded Metal Mesh?

Expanded metal is a type of sheet metal which has been cut and stretched to form a regular pattern (often diamond-shaped) of metal mesh-like material. It is commonly used for fences and grates, and as metallic lath to support plaster or stucco. Expanded metal is stronger than an equivalent weight of wire mesh such as chicken wire, because the material is flattened, allowing the metal to stay in one piece. The other benefit to expanded metal is that the metal is never completely cut and reconnected, allowing the material to retain its strength.

One of the most popular hole shape is diamond because of how well the shape absorbs energy and resists mechanical deformation after installation. Other design considerations are the size and angles of the shapes, which will also affect how well the metal absorbs energy and where the energy is spread throughout the expanded metal.

For the diamond shape, there are at least four different angles that come into account, the two acute and two obtuse angles. The larger the angles, the less strength the shape will have because there would be too much space inside the shape. However, if the angles are too small, strength is lost because the shape is too close together, so there is no space for the structure to hold.

In conclusion, expanded metal mesh have more stronger strength than others. And according to different application place, we can change the hole angles to achieve the best effects.

2. Which places can we see the expanded metal mesh?

Expanded metal is frequently used to make fences, walkways, and grates, as the material is very durable and strong, unlike lighter and less expensive wire mesh. The many small openings in the material allow flow through of air, water, and light, while still providing a mechanical barrier to larger objects. Another advantage to using expanded metal as opposed to plain sheet metal is that the exposed edges of the expanded metal provide more traction, which has led to its use in catwalks or drainage covers. Large quantities of expanded metal are used by the construction industry as metal lath to support materials such as plaster, stucco, or adobe in walls and other structures.

In the three-dimensional dimension of our life, we can find expanded metal mesh from the bottom view, the eye level, the top view as well as invisible place.

A. From the bottom view raise your head, you might find the ceiling of the building is made of expanded metal mesh. Especially in recent years, expanded metal mesh is a kind of decorative material used in interior decoration ceiling. From the perspective of the word “decoration”, it must be at least appreciative and practical, and also have the selectivity of different preference for users.

There are some common specifications used for ceiling:

• Material: low carbon steel, 304 stainless steel, aluminum, iron ect.
• Hole shape: Diamond and hexagonal
• LWD x SWD x Strand Width: 40-80mm x 20-40mm x 1.5-5.0mm
• Surface treatment: Powder coated, galvanized, PVDF, anodizing etc.

Ceiling expanded metal mesh is of the features of aesthetic, strong practicability, good ventilation, light permeability, sound absorption, simple construction, convenient daily maintenance and low cost. Our installation is also easy to install and maintain. It is suitable for indoor ceilings such as hotel lobby, railway station waiting room, platform, conference hall, entertainment hall and large workshop etc.

B. From the eye level, you might find the surrounding such as facade cladding and fencing guardrail for exterior decoration.

For facade cladding, expanded metal mesh not only improves the strength and hardness of the decorative material, but also reduces its own weight. And the raw materials are also fully utilized with a flat and beautiful surface. It also has the features of good light transmission performance, good ventilation performance, acid and alkali resistance, suitable for various air pollution environment, simple construction and daily maintenance, durable and have long service life etc. Common materials are aluminum, stainless steel, iron etc. Common shapes are diamond, rectangle, strip, flower shape etc.

For fencing guardrail, expanded metal mesh is also called anti-glare mesh, which can not only ensure the continuity and lateral visibility of the facility, but also isolate the up and down lanes so as to achieve the purpose of anti-glare and isolation. The expanded metal mesh fence has the characteristics of economy, beautiful appearance, and wind resistance. As it is double-coated with galvanized and plastic-coated, so it could extend the service life and reduce maintenance costs. Easy to install but not easy to damage, the contact surface is small but it is not easy to get dust. It can maintain the special shape for a long time and specifications can be customized.

Fencing expanded metal mesh is widely applied as barrier in highway anti-vertigo nets, urban roads, military barracks, national defense borders, parks, buildings, villas, residential quarters, sports venues, airports, road green belts, etc. And it also used in urban viaducts, high-speed anti-parabolic protection for highway overpasses, railway bridges, culverts, overpasses, and ports and docks etc.

C. From the top view, you could find expanded metal mesh be used as walkways, construction plate-form etc.

The walkway expanded metal mesh also named as heavy steel plate mesh which is of large bearing capacity. It also known as expanded metal plate mesh, steel plate stretched mesh, diamond plate mesh, pedal mesh, trample mesh, platform pedal mesh, springboard mesh, etc. It can be used as the working platform of high-altitude working platform foot net, heavy machinery and boiler, oil mine well, locomotive, 10000 ton ship, etc., as well as the construction industry, highway, railway bridge for reinforcement. This product has become a special screen product for ship manufacturing, building scaffold pedal, oil field working platform, power plant working platform and automobile manufacturing workshop working platform.

1. All the above applications are visible. However, in the invisible places, there are also existence of expanded metal mesh — plaster or stucco mesh.

Plaster or stucco mesh belongs to micron mesh, which with a thickness about 1.0mm is made of high-quality low-carbon steel material stretched by a precision punching machine to form a uniform diamond-shaped metal mesh surface.

According to the “Code for Acceptance of Quality of Architectural Decoration Engineering” 4.2.5: The key to the quality of the plastering work is firm bonding without cracking, hollowing and shedding. If the bonding is not strong and there are defects such as hollowing, cracking, etc., it will reduce the protection of the wall and affect the decorative effect. Therefore, a layer of reinforcing steel mesh should be nailed on the surface of the substrate, so that the surface of the substrate is integrated with the gray layer to prevent cracks from occurring, and no defects such as hollowing appear. In response to this serious problem, combined with various climate temperature gray numbers and other factors, we developed this kind of light-weight, high-tensile strength, convenient construction wall stencil expanded metal mesh.

In a word, expanded metal mesh has so many applications. And as you see, according to different application, there are different type of expanded metal mesh. Whatever the application, using expanded metal mesh in construction could make the building simple and elegance to achieve both the practical and aesthetic effects.

3.What are the factors to select building material and supplier?

Procurement exists in a dynamic, fast-paced, constantly changing environment. So surely the reasons we use to select our suppliers and supply partners would change over time too? Wouldn’t they?

Gone are the days of the cheapest price (or at least they should be!). Even the list below, the key factors highlighted years ago out, may have been superseded. So what are the new criteria? Or, if they are still the same, why is this the case?

If we take a look back at the responses from the network 5 years ago, we find ourselves looking at a list with a number of the usual suspects on it:

• Cultural Fit – including values
• Cost – covering price, Total Cost of Opportunity/Ownership
• Value – value for money and value generation opportunities
• Experience in the market and current references
• Flexibility Response to change – in orders and products
• Quality – covering products and service quality and quality history

In addition to this, some that didn’t make the top 7 as it was included trust and professionalism, strategic process alignment and technical ability. There’s nothing that looks out of place on the list. In fact, they’re all eminently sensible and fair criteria to be considering. However, the problem is it that it reflects a very traditional view of procurement.

In a recent study, the most common criteria still were years in business and financial stability, which include:

• Price/Cost
• Quality and Delivery
• Reliability
• Communication
• Cultural Match

Let’s analyze one by one. We are a factory producing expand metal by ourselves, if you choose ours, which means you can get this kind of material from a factory with a factory price directly with any commissions during this transaction so that save the cost for you.

About quality and delivery, Dongjie has strictly quality control and professional production line. Our quality control from the very beginning of the material to the out going shipment inspection has specialized QC team and salesman to carry out a whole serious test to make sure delivery in time and qualified quality.

Reliability or dependability is used in a variety of business and industrial settings. In general, the concept of reliability is applied where it is important to achieve the same results again and again. A manufacturing process is said to be reliable when it achieves the same results, within defined limits, each time it occurs. An automobile, or other type of product, is reliable if it performs consistently and up to expectations. About this point, Dongjie could promise our quality of products and service will always be the same.

About communication and cultural match, we think highly both the communication of coworkers and clients. Our sales dept., production dept., QC dept. and delivery department will work as a team to serve customers which make our service timely and effective. Professional sales will supply high efficiency and timely communication. E-mail, Whatsapp, Skype, each method could reach to us. We attend exhibitions and organize customer visiting every year which help us have a deep talk with customers about our cooperation.
