Screenguard 316 Stainless steel security mesh is an important part of a security door and Windows, its quality seriously affects the performance of security doors and Windows. What factors affect the quality of the Stainless mesh? They include the following:
The Steel Wire
- Material used for the steel wire.
The Screenguard stainless-steel security mesh is made of steel wire. Stainless steel grades are determined by their composition and uses. 316 and 304 stainless steels are the most common types.304 which is often referred to as 18-8 (18% chromium, 8% nickel) is a basic stainless alloy that offers a combination of corrosion resistance, heat resistance, strength and affordability. Screenguard 316 mesh contains an additional substance, about 2 to 3 percent molybdenum, which increases corrosion resistance, it has a higher level of corrosion resistance, particularly in a salt-water environment. Darley’s 316 mesh is more suitable for Australia’s coastal environment and the inland environment can choose 304.
(2) The diameter of the steel wire.
The most commonly used stainless steel wire used in Australia is 0.8mm. It is easier to weave, and offers a more consistent quality, the thicker the diameter of wire the more difficult the weaving process. With 15 years of production experience manufacturing 0.8mm 316 mesh, we believe we have produced a stronger security mesh to keep you and your family safe.
(3) The tensile strength of the steel wire.
Tensile strength is the maximum carrying capacity of a metal under tensile conditions. At the same wire diameter, tensile strength is a key factor for 0.8 316 security mesh to pass knife shear test (AS5041-2008).
Weaving process.
The wire used in 316 security mesh is relatively thick, which places high demands on the weaving equipment. Good quality equipment determines whether the aperture is square and the mesh surface is flat. So good quality weaving machines is a must to produce high quality 316 stainless steel security mesh.
The surface treatment of the mesh.
Powder coating is a type of coating that is applied as a free-flowing dry powder. Unlike conventional liquid paint which is delivered via an evaporating solvent, powder coating is typically applied electrostatically and then cured under heat. The powder may be a thermoplastic or a thermoset polymer. So, the use of a good powder is a key factor in 316 security mesh quality.
Pre-treatment An absolute prerequisite for successful powder coating is that the surface to be coated must undergo pre-treatment to clean and decontaminate.
Contamination of the surface may give rise to aesthetic defects in the coating (bumps, craters, etc.) and may cause poor adhesion between the coating and the base. The most typical contaminants are oil and grease, surface corrosion, mill scale and what can collectively be called particles – both loose and fixed.
