Molded FRP Grating Weight: Panel, Cut Piece and Shipping Inputs

Reviewed by Yadong Wang, Technical Engineer · Published by QY Metal Tech

A molded FRP grating weight chart gives kg/m² for a specific construction, not one weight for every fiberglass panel. In QY's published parameter chart, the eight open-grating rows below range from 12.3 to 35 kg/m². Match the row before calculating: panel net weight = finished area × the matching kg/m² value. Packing is added separately to obtain shipment gross weight.

Molded FRP grating weight chart (kg/m²)

These are reference values transcribed from the QY parameter chart shown above. They describe that chart, not a current stock list or a load rating. Confirm the ordered construction, surface and unit weight on the quotation. The source labels the three dimensions below as “grating dimensions”; they are reproduced without reinterpreting the first two as clear openings or center spacing.

Depth alone does not identify the weight. The two H38 rows are 19.6 and 24 kg/m² because their listed geometry differs. Likewise, do not apply the H50 50 × 50 row's 21.5 kg/m² to the H50 38 × 38 row. Covered panels and pultruded grating need their own product data; a steel grating weight calculator is not a substitute for FRP data.

Worked example: one panel and an order

The chart lists a 1.22 × 2.44 m panel size. Using that finished rectangular area and the H38 38 × 38 × 38 reference row:

This is an arithmetic example using the published row and dimensions, not a measured shipment. Retain unrounded intermediate values and round the final total. Ten panels rounded individually to 58.35 kg would total 583.50 kg instead; stating the rounding method makes the difference understandable.

For a rectangular cut piece, replace the dimensions with its finished length and width. Calculate each different size and construction separately before adding quantities. For irregular cutouts, agree whether the estimate uses finished area, parent-sheet usage or another stated basis; do not infer area from a photograph.

Unit, panel, order and packed weights

The table cannot determine pallet or crate weight. Packing depends on panel dimensions, stack arrangement, edge protection, handling and accessories. Request the proposed packing configuration and gross weight instead of adding an assumed percentage. Compare freight quotations on the same net/gross basis.

Information to send before ordering

Send the chosen row or product description, source and confirmation date, finished dimensions, quantity, surface requirement, cutouts, accessories, packing requirements and destination. Ask QY to confirm unit weight, order net weight and packed gross weight as separate figures.

Use the molded FRP grating product page to identify the product family. For structural selection, use the FRP grating load and support-span guide: weight and depth alone do not establish allowable load, clear span or deflection. When the panel schedule is ready, send dimensions and packing requirements to QY.
