About S4S Wood Boards

We start with rough lumber over sized as cut by the sawmill. We then take these rough sawn boards and surface them through a planer to a nice much more consistent size. Our S4S square edge products are smooth surfaced for thickness and width.

These boards are much easier to install than our standard rough sawn material.

Apitong, Keruing 1-1/2" x 7-1/2"

For our S4S boards we generate a net thickness of 1.5” and net width of 7.5". This material is run through a planer to achieve a smooth finished and dimensionally uniform board which is planed/dressed on all four sides, resulting in a uniform size, shape, and texture. It has been surfaced to remove roughness, imperfections, and irregularities.

About Std + Btr

Standard and Better is the typical grade for most truck trailer or industrial applications. In tropical hardwood this means few if any knots, no structural defects, and scattered pin hole is allowed. We inspect all shipments of material at the source with our own quality control personnel.
