Fibergrate

Try replacing those areas with high load capacity fiberglass grating. Whether you need a large open area for fast draining or tight grate openings for ADA surfaces, Trench Drain Systems offers custom fiberglass products for your drainage application.Fiberglass grating can be molded into large sheets for later fabrication into smaller, custom shapes. Mesh grating is made by laying fiber reinforcing materials in grid work shaped mold and bonding them with polyester or vinyl ester resins. Other resins are available for special applications. The molded product is ground to the desired thickness and flatness. Slip resistant coatings are applied to the surface at this time, if required. Trench Drain Systems offers the following molded fiberglass grating products.

High load capacity molded grating is commonly used in applications where heavy loads (such as fork truck traffic) are encountered in corrosive environments. Also, HLC grating has been used in areas where cast iron grates are prone to theft, as they have no metal scrap value. HLC mesh (1″ x 2″) is made with high strength vinyl ester resins and come in 1.5″ and 2″ thicknesses. Non-slip surface coatings are available.” Open area is 48%. Grating weights are 6.2 and 8.4 pounds per square foot, respectively.

Pultrusion is a fiberglass forming process whereby reinforcing fibers are pulled through an extrusion die while vinyl ester polymer resins are extruded under pressure. The act of “pulling” fiber while “extruding” resin leads to the term “pultrusion”. Fiberglass shapes made by this process come in long, continuous shapes. In the case of fiberglass grating, the shapes have cross-section akin to rectangular bars, tees and I’s. To make bar grating, these long bars are assemble parallel to each other and connected by structural cross members (known as tie bars) on 6″ spacing. A non-slip coating is applied to the grating after assembly.

This type of bar grating is especially good for pedestrian surfaces that need to be ADA approved. It is available in 1″, 1.5″ and 2″ bar thicknesses. Open area is mostly under 40%. T-Bar grating is available in 12% open area with a fine slip resistant coating that is used in water parks and boat dock decking.

A molded fiberglass with ¾ inch opens built on a 1.5″ x 1.5″ frame. It comes in 1″ and 1.5″ thicknesses. Micro-mesh can be made with or without a slip resistant coating. Open area for Micro-mesh is 44%. The weight is 2.9 lbs per square foot for the 1″ thick mesh and 4.5 lbs per square foot for the 1.5″ thick mesh. Micro-mesh is available in light gray and dark gray.

Molded mesh grating is one of the most common types of fiberglass grating. It is available in a 1″, 1.5″ and 2″ square mesh. Thicknesses vary from ½” to 2″. And, resin types can be varied to meet your corrosion and fire resistant needs. For standard trench drain applications, polyester resins are used most often. Open areas for mesh grating range from 58% – 87%.

Available in 1″ and 1.5″ heights, I-Bar load bar spacing is on 1″, 1.5″ and 2″ spacing, which also defines the open area of the grating. I-Bar grating that have load bars on a 1″ spacing (I4010 and I4015) are ADA approved with 40% open area.” I-Bar grating is available in polyester resin (yellow) and vinyl ester resin (dark gray).

I-Bar grating is available for use in applications where heavy loads will be experienced. Available in 47% and 58% open area (1.19″ and 1.5″ bar spacing), high load capacity bar grating is made in 1″, 1.5″, 2.0″ and 3″ thicknesses. Slip resistant coatings are a standard feature for this product.
