Galvanized Corrugated Steel Plate Description What is Corrugated Steel Plate and what is it used for? Corrugated sheet metal is produced by stretching a sheet of metal and then rolling it through a rolling die to create a linear, wavy pattern of crests and troughs; they are laid next to each other and are mainly used in outbuildings, barns, industrial warehouses, agricultural applications And waterproof roofs for commercial buildings, where aesthetics are less important, but waterproofing is important. In recent years, corrugated roof panels have been used as cladding in bars and clubs to add an industrial or gritty urban feel. This form of corrugated profile metal sheet or sheet is also commonly referred to in the building industry as roof cladding; they are usually installed with a half-corrugated overlap to make it waterproof, our corrugated steel roofing sheets are galvanized to increase the protection and corrosion resistance. The benefits of using corrugated steel sheets in your projects; - highly robust - light weight - Weather and corrosion resistant - excellent quality of protection - easy to install Complete your corrugated roof sheet. Corrugated steel roof sheets are galvanized to provide a highly corrosion- resistant surface, so no further painting or other surface treatments are required to improve the for extra protection. However, for aesthetic purposes, galvanized products can be painted or powder coated if desired. Order corrugated steel roofing sheets from Hebei Shineyond. Introduction Galvanized Corrugated Steel Plate is pressed from galvanized or galvalume coils and can be produced in different tile shapes as required. Usage Gi sheet is widely used in roof panels, wall panels, floor panels and ceiling panels.

Checkered Steel Plate Description Checkered Steel Plate is a steel plate with a raised (or recessed) pattern on the surface. The pattern is lentil-shaped, diamond-shaped, round bean-shaped, and mixed flat and round shapes. The lentil shape is the most common in the market. The pattern can be a single diamond, lentil or round bean shape, or a combination of two or more patterns to become a combined pattern plate. Due to the diamond pattern, the risk of slipping is greatly reduced. Checkered Steel Plate is commonly used in structures such as stairs, ramps, walkways and vehicle interiors. It can also be found in construction applications. Checkered Steel Plate Precautions 1. After the materials are transported to the site, they should be stacked according to the specifications and installation positions, and the square wood should be padded to prevent the rain from scouring. The stacking height should not be too high to prevent deformation caused by being overweight. 2. In order to meet the requirements of the overall construction progress, the laying of the patterned steel plate is closely connected with the installation of the steel structure. After a certain stage of anti-corrosion work on the steel beam, the patterned steel plate can be laid. The laying sequence is the same as the steel beam installation sequence. 3. On the patterned steel plate, the lifting lugs are welded on the ground, and the holes to be welded on the secondary beam and the frame beam are cut with flame. The size of the opening is 6mmx12mm, and the spacing is not more than 0.5m.

A biconvex lens means that both surfaces of the lens are convex. Its focal length is positive and mainly for the function of focusing. It is commonly used in imaging relay system and object imaging at finite conjugate distance. The smaller the conjugate ratio is, the smaller the aberration will be. Oplens can not only customize the common plano-convex lens of N-BK7 or fused quartz, but also customize the biconvex lens of any glass material. You are welcome to contact us for customized biconvex lenses.

An achromatic lens is a lens designed to minimize chromatic aberration and spherical aberration. Two-plate achromatic lens is one of the simplest achromatic lenses, which can be divided into two types: double agglutination and double dissociation. Of course, achromatic lenses can also be composed of multiple lenses, depending on their uses. The achromatic lens with large aperture is usually separated and assembled in the frame with excellent comprehensive performance. Achromatic lenses are widely used. A multi-lens optical system usually consists of several achromatic lenses. High quality microscopic objective lens and photographic lens are all complex lens combination systems which eliminate both achromatic and other monochromatic aberrations. Oplens can produce single layer or multi-layer anti-reflective films with all kinds of coating materials on both outside surfaces. Their performance is superior to that of all single element lenses.

The biconcave lens, also named double concave lens, is usually made of flint glass and used for beam divergence. It’s focal length is negative but the parallel incident ray diverges outward. The two sides of the biconcave lens curvature radius can be equal or not. Combined with plano-convex lens, it is generally used in beam expanders, projection optical systems and optical viewers, etc. Oplens can not only customize the common plano-concave lens of N-BK7 or fused quartz, but also customize the biconcave lens of any glass material. You are welcome to contact us for customized biconcave lenses.

A plano-concave lens is a lens that has a flat surface on one side and a concave surface on the other side. The focal length of a plane-concave lens is negative, allowing the beam to diverge.  Therefore, it can be used in optical system for beam expansion, light projection or to increase focal length.   Oplens can not only customize the plano-concave lens with common materials of N-BK7 (Shott) and fused silica, but also customize the plano-concave lens of any glass material.     You are welcome to contact us for customized plano-concave lenses.

Oplens Plano-convex lens is an optical lens in which one side of the lens is flat and the other side is convex. The focal length of plano-convex is positive, mainly for the role of focusing. The collimating beam can be gathered on the rear focus or the point light source can be transformed into a collimating beam. Plano-convex lenses are widely used in optical display system, optical projection system, optical imaging system and laser measurement system.   Oplens can not only customize the plano-convex lens with common materials of N- BK7 (Shott) and fused silica, but also customize the plano-convex lens of any glass material.     Parameters Material: Surface Flatness: Scratch/Dig: Eccentricity: Foca , l Length Tolerance Diameter Tolerance: Thickness Tolerance: Clear Aperture: Coating: Diameter Range: Optical Glass < λ/5 @ 633nm < 40/20 (both sides) ≤ 1arcmin < ± 1% < + 0.00/ - 0.02mm < ± 0.05 ≥ 95% of diameter AR OR BBAR  5~260mm Oplens is one of leading optical elements and spherical lens manufacturer.

Negative meniscus lens A meniscus lens is a lens with two spherical surfaces, convex on one side and concave on the other. The lens provides a smaller beam diameter to reduce beam waste and spherical aberration. When one meniscus is combined with another lens, the focal length is shortened and the numerical aperture of the system is increased. This reduces image distortion and improves image resolution. There are two types of meniscus lenses: ● Positive meniscus lens The positive meniscus lens is used for applications requiring small focal numbers (less than 2.5). For focal lengths between 2.5 and 10, a meniscus lens minimizes spot size and improves image quality. The concave side curvature of a positive lens is smaller and the convex side curvature is larger. Frequently used for beam focusing applications Minimizes the increase in spherical aberrations for multi-element systems ● Negative meniscus lens The negative meniscus lens is used for applications using infrared materials with a high refractive index. These lenses serve as substitutes for other negative lenses with greater curvature on the concave side and less curvature on the convex side. They are used in beam spreading applications where minimal spherical aberration is required. Frequently used for beam expanding applications Minimizes the increase in spherical aberrations for multi-element systems Parameters Material  Optical Glass Surface Flatness  < λ/5 @ 633nm Scratch/Dig  < 40/20 (both sides) Eccentricity  ≤ 1arcmin Focal Length Tolerance  < ± 1% Diameter Tolerance  < + 0.00/ - 0.02mm Thickness Tolerance  < ± 0.05 Clear Aperture  ≥ 95% of diameter Oplens provide custom optical components, we can custom sizes and shapes.
