Force reduction is the essential characteristic that identifies whether the shock absorbing ability of a sports floor is appropriate for its athletic use. This factor indicates if the surface is safe, comfortable, high performing and suitable for the requirements and specifications of a project. ASTM test methods evaluate the effects of generated impact force on a playing surface and how it interacts with a body’s joints. Different floor surfacing products conform to various levels of cushioning. The choice of flooring should then be greatly influenced by the expected and defined plan of usage.   The levels form different categories from 1 to 5 in order to help sports facility managers in their decision. This facilitates the selection of the most appropriate floor surfacing solution for the activities that will be taking place in the facility. Category 1 (10% – 21% Force Reduction) Typically recommended for low degrees of physical activity in non-sports rooms or areas. Can easily a...

Metal screens   have plenty of practical applications in residential and commercial structures. These screens can serve as a decoration, a functional component of the building or fulfil both roles at the same time.   Whether fabricated as a standard size panel or customised for unique projects, metal screens can address a wide range of widespread aesthetic and practical needs. There are also some less common applications in which these screens can be just as useful. Let's look at a few of them:   1. Branding and identification   Decorative metal screens  may not be the first thing that comes to mind when your business starts to consider opportunities around branding your building or helping visitors identify it. But improvements in the tools and processes used to create screens have led to a variety of options on this front.   Our ARES screens offer the opportunity to faithfully reproduce many logos, images and abstract patterns with a high degree of accura...

Polyurethane waterproofing materials   are widely used in construction, civil engineering and various other industries due to its excellent performance characteristics.     Advantages Durability PU waterproofing materials have excellent durability and can last for several years without showing any signs of deterioration. Waterproofing PU waterproofing materials have excellent water resistance, making it an ideal choice for waterproofing structures like roofs, basements, and underground structures. Flexibility PU waterproofing materials have excellent flexibility, which allows it to withstand movement and expansion of the structure, without cracking or losing its waterproofing properties. UV resistance PU waterproofing materials are resistant to UV rays, making it suitable for outdoor applications, where exposure to direct sunlight is a concern. Chemical resistance PU waterproofing materials are resistant to a variety of chemicals, including acids and alkalis, making ...

There is no better way to make your pool stand out in the water than with decorative tiles. Whether it's residential or commercial waters, a   glass mosaic tile  installation can take your pool to a new level of luxury. But how do you choose which tiles will stand the test of time, and how do you care for them? How do you install them and what are the best applications? Don't worry, the guide to installing mosaic pool tiles is here. Your top choice Now you can buy glass mosaic tiles that are glued to individual tiles with a paper surface. If you want to cover a very large area with tiles, then you should definitely consider the sheeting option. If you are traveling abroad and find small, unique tiles that you want to incorporate, then choose a pattern that is loose and spread out. How to cut If you choose a tile pattern that requires sections of different sheets, then simply cut the paper, mesh support or plastic sheeting that holds the tiles together. You should use a new sha...

  Corrugated Culvert Pipe 5 precautions before the construction of  corrugated culvert pipe 1. Before culvert construction, prepare relevant materials, personnel and equipment to enter the site, and do a good job of safety protection during the construction period, fence the slope of the roadbed to prevent stones and other objects from slipping and injuring people. 2. Foundation treatment, backfill sand and gravel or masonry chip concrete. Level the substrate, refill 30-1250px thick sand and gravel material. 3. steel corrugated culvert pipe construction, using the method of segmental construction, in advance in the original arch culvert substrate with two angles side by side, the length is determined according to the culvert length. For the steel culvert pipe to advance the slide rail, corrugated culvert pipe diameter according to the needs of the project can have different specifications, the whole pipe diameter for 0.5m - 2.5m; each section of the pipe length of about 3 mete...

Choosing the right  pump  for your slurry application can be a daunting task due to the balance of many factors including pressure, flow rate, abrasiveness, viscosity, particle size and particle type. There are several types of pumps suitable for pumping slurries, but there are some important factors to consider before deciding which technology to use. You can follow these four simple steps to determine which type of slurry pump is best for your particular application. 1. Determine the Nature of the Material Being Pumped Consider the following. Size, shape and hardness of the particles (which affect the potential for wear and corrosion of the pump components), corrosiveness of the slurry. 2. Consider the pump components If it is a  centrifugal pump , is the design and material used to manufacture the impeller adequate to pump the slurry? What types of materials are used to manufacture the pump? Are the pump discharge components suitable for the slurry being pumped? What i...

Composite materials like FRP or fiber-reinforced plastic are used commonly in manufacturing and construction. As a composite material FRP has many advantages that make it extremely durable, even when exposed to a corrosive environment. It is used in the handling of all kind of materials, including, their storage and transfer. ​ One of the most commonly seen applications for FRP is  FRP pipes . Laid underground, overhead, in seawater as well as factories, FRP pipes find common usage because of their load bearing capacity and resistance to corrosion. Although it is seen as a modern product, the history of FRP is actually quite old, dating back almost 65 years!     History The first product that can be labeled as an FRP product is Bakelite. It was invented by Leo Baekeland who was actually looking for a replacement for shellac. In 1905 it was while he experimented with formaldehyde and phenol that he stumbled upon various compounds. One of these was hard material that could ...
