The concave surface (meniscus top grating) provides superior slip resistant footing in most environments including wet or oily conditions and is the standard surface for molded gratings.

The Concave surface - original type of grating surface which has curves inwards during the thermosetting process.
The concave edges received at by this process ensure good anti slip properties.

Concave Grating is more suited to low foot traffic areas and is particularly suitable for hygiene applications where a high standard of slip resistance is needed and ease of cleaning is a consideration.

Open mesh GRP Gratings with concave surface are produced in special matrix molds. After the material hardens, the GRP gratings are pressed out of the mold.

The grating consists of three main components: Resin Mix, E-class Fiberglass , Pigments.
The percentage of resin and fiberglass - aprox. 70% to 30%.

Fiberglass is located in TWO directions.
✔ Corrosion and Chemical Resistant
TATRAGRATE is particularly designed to provide safe, long- lasting, economical and worry- free solutions in environments where chemicals and other corrosives attack metal, wood and similar materials.


✔ Fire resistance
SLAVIA GRATINGS TATRAGRATE has been tested in accordance with EN 13501-1 + A1:2009. Test reports are available on request. Special fire retardant requirements can be met with extra additives.


✔ Impact resistance
The impact resistance of SLAVIA GRATINGS TATRAGRATE FRP allows repeated deflection without permanent deformation. A certain amount of deflection can occur with loading. Unlike metal grating fibreglass has a good memory, so once the object is removed the Fibreglass Grating will fully recover to it's original position.


✔ Life Span
More than 30-40 years of useful life is guaranteed for SLAVIA GRATINGS TATRAGRATE


✔ Cost effectivenes
Initial purchase cost of FRP Grating compares favourably with steel grating but the real saving is made on the superiour life expectancy and zero maintenance costs. Also installation costs are usually less than that of steel grating.


✔ High strength - to- weight ratio
It is integrally constructed for strength, and is less than one- half the weight of steel grating allowing easy removal for access and installation with no heavy equipment and reduced manual handling risks.

Specification Standard Series
Series Resin Type Fire resistance Description Color
ECONOM NON FIRE Orthophthalic Resin + For use in water/ wastewater or air-ageing applications, light industrial application and in the wave zone areas of offshore platforms where the environment is moderate. It still offers superior performance to traditional flooring products such as steel, aluminum and wood and is the most economical resin available.

Cutting and Installation GRP Gratings can be installed in standard panels or we can CUT TO SIZE according drawings.

When cutting or drilling, always wear protective glasses or goggles and a face mask which covers the face and mouth. Always use of barrier creams on exposed skin.

Standard Cutting Molded Grating is ideal for applications requiring extensive cut outs for pipe, duct and electrical penetrations, access holes.
Bi-directional cross-grating structure allows various options for cutting without additional support, treatment. The strengthening of edges is not necessary.



GRP products can be cut in a production environment using large vertical saws or small saw.
There are several types of cutting:
Straight line standard cutting performed by large vertical saw;
Cut-outs and Curve cutting - cutting performed by small saw.

Gratings, Stairtreads and Plates can be easily cut to size on site. All the necessary components for sealing will be supplied.
Closed Edges Cutting What is "Closed Edge" mean?
GRP Gratings in standard dimensions always have Closed Edges. But during cutting to size, parts whose external dimensions deviate from production dimensions might not have closed edges.





That's why special Closed Mesh Table was made when closed edges are required.
Closed edges are required, if the parts will be fastened to each other.



When you will need gratings with Closed Edges please inform your manager about this special requirements and he will optimize your cutting plan.
Blocking Molds What does blocking costs mean?

GRP gratings are produced on the mould form with standard dimension - standard panel size. We can produce gratings on the blocked mould form to minimalize waist. As example we can block our 1220x3660x38 (mesh 38x38) mould for length 3000mm to receive 1220x3000x38 or we can block our 4038x1000x30mm (mesh 19x19) mould for length 3000mm to receive 1000x3000x30.

This option is beneficial only if Extra Cost for Blocking is less than Extra Cost for Standard cutting.
Recommendations for Installation Use installation drawings during montage. Always pay attention to terms and conditions of the environment. Attention to safety during installation. We recommend that all sides of molded square mesh grating panels be supported. It provides the highest loading limits within the selected deflection criteria.
Installation instructions and Deflection
Please check which load capacity is required: type of load, traffic intensity. It will help you to make correct choice of GRP Gratings Mesh Size and height. To calculate the optimal width of the span is necessary to download the Deflection tables and Installation instructions
Gratings must be fixed by clips to the surface always. We recommend to use of hold-down clips to position grating panels on supports. Don't use clips to reduce the deflection, clips don't change standard deflection. Use six hold down clips per full panel (four per one-half panel). It is forbidden to use less than four clips per one panel. In case high wind loads or where uplift of the grating could be a problem, we recommend extra clips. Four clips are also recommended on every stairtred. In case when grating is supported at two sides (walkways) use type "F" clips to prevent excessive movement of the panels relative to each other. We recommend supports at the edge of all panels.
Read more about Mounting Accessories
Mounting Accessories We recommend to use of hold-down clips to position grating panels on supports.
We highly recommended to connect gratings by clips all around the gratings with 4 clips per one square meter in generally. Use six hold down clips per full panel (four per one-half panel). It is forbidden to use less than four clips per one panel. In case high wind loads or where uplift of the grating could be a problem, we recommend extra clips.

Don't use clips to reduce the deflection, clips don't change standard deflection.

Mounting Clips for GRP Gratings Mounting Clips for GRP Gratings are made from Galvanised Steel, A2 stainless steel (1.4301, AISI 304) and the corrosion resistant grade A4 stainless steel (1.4401, AISI 316)
B/B1/B2 Clips type B,B1,B2 are sophisticated and used without drilling support of the gratings. For B clip the cross bar in Micromesh gratings have to be cut out for the recessed plate designed for mesh 38x38mm.
Bottom part of clips B you can put down through the hole 38x38mm and assembly can be from top only.
M/S/W The installation of clip M, S and W is easy, but the supporting beam has to be drilled. M saddle we recommend replaced by recessed plate from clip S for the micromesh gratings and another gratings too. Recessed plate better stick than M clip and in case big warping M saddle can damage edges around clips. We can to say that recessed plate is more friendly to the grating like M saddle.
W-clips are specially designed to mount covered gratings. The covered plates of the gratings and the supporting beams have to be drilled. W clips are suitable for Micromesh gratings and for the every type surfaces too.
F/F1/F2 In case when grating is supported at two sides (walkways) use type "F" clips to prevent excessive movement of the panels relative to each other. F clips are designed to connect divided unsupported gratings to each other to prevent excessive deflection.

Take care "open" forded gratings always meet closed mesh gratings when used.
Gratings must be fixed by clips to the surface always. We highly recommended to connect gratings by clips all around the gratings with 4 clips per one square meter in generally. We recommend supports at the edge of all panels. Gratings are elastics and after fixing they will be straight
