Floor Gratings

Floor gratings encompass a wide variety of grates used for flooring or as supplements to improve flooring characteristics such as grip. Grates are a framework of metal or fiber reinforced plastic bars and sheets that are perforated or otherwise slotted to create a grid. In flooring applications, metal grates or plastic grating offers several advantages over solid surfaces.

Floor gratings are valuable utilities in a variety of applications. The grid work creates a textured surface which improves slip-resistance and reduces the risk of falls. This risk is further diminished by drain grates in floors which permit the passage of liquids and debris such as water and oil that might otherwise prove hazardous.

Air, sound and light can also pass through floor gratings which help improve ventilation and visibility in factory and warehouse environments. Refrigeration, heating, oil and gas, power, metal, mining, chemical and food processing, and pulp and paper industries often utilize this particular type of grating in their manufacturing facilities.

Additionally, outdoor applications such as bridges, docks, city streets and sidewalks employ floor grates for traction and drainage purposes. In these instances, the grating is most commonly used as the floor itself. Other grates can be additions to existing flooring, installed as a top layer to improve traction.

As these are typically applied to solid surfaces, however, they are not adequate drainage devices. Mobile grates are also available to be put in place for a specific process or use, and are easily removed when no longer required.

As aforementioned, floor gratings can be made of metal or fiber reinforced plastics such as polyester and vinyl ester resin. The two types inherently require different manufacturing techniques. Expansion metal grates are created when metal is slit and then expanded through heat and pressing techniques.

This option is popular as it generates no waste. Alternatively, punch presses are used to knock out hole patterns in metal sheets. Common metals for either method of fabrication include stainless steel, iron, brass and sometimes aluminum.

Fiberglass reinforced plastic gratings are produced by weaving continuous strands of fiberglass through thermosetting plastics before cooling. Additionally, both metal and plastics can be formed into bar grating, which is used in heavy duty applications for constant use or heavy load bearing.

Bearing bars, cross bars, and square, rectangular or circular mesh grates are widely available for flooring. The size of perforations or gaps between the grate bars varies greatly and is therefore one of the most important considerations.

This determines what may pass through the grate, for example water or debris, while also having a significant impact on visibility for both interior and exterior applications. Standard perforation sizes are regulated in many factory environments which require proper ventilation and fluid drainage.
