Description

Made to Your Drawings, Not the Nearest Metric Size

12.7mm matters when the drawing tolerance does. Wherever panels meet machined parts, gaskets, or each other in a stack, a 0.7mm offset repeats at every interface and shows up at final assembly. Non-standard thickness production means the board is extruded to the number on your drawing rather than to the nearest metric gauge in the standard range.

Structure Options Across the Product Range

A 1/2″ board can be produced in the structure that fits the job. Celuka offers a hard skin of roughly 0.1 to 1mm at Shore D65, which machines cleanly and gives edge banding a good bonding surface. Co-extruded board carries a harder solid skin of 0.2 to 0.8mm at Shore D68 for applications that see frequent handling or weather. Free foam is a uniform closed-cell structure from 0.35 to 0.60 g/cm³, the light and printable option. The technical team confirms the right structure with you once the application is specified.

Density Dialed to the Load

Density runs from 0.35 to 0.80 g/cm³ depending on the board type and the application. Structural panels that carry weight are produced at higher densities, while display and signage work is often better served at the lower end of the range. On a custom run, the density you specify also sets most of the resin content per sheet, so the quote follows the load the board actually carries rather than the top of the range.

Colors and Finishes to Match the Job

Color and finish follow the structure chosen for the run, and both are confirmed as part of the custom specification rather than selected from warehouse stock. The color list by board type is in the specification table below. Surface options include double-sided sanding for tighter thickness control and a protected film finish for transport.

The Conversion That Matters: 1/2″ = 12.7mm

One half inch is exactly 12.7mm. The metric gauge closest to it, 12mm, is not the same product. The difference is 0.7mm, which is small enough to ignore in loose applications and large enough to matter in precise ones.
