400×45 H2S F17

400 x 45 LVL F17 H2S is a heavy-duty engineered LVL section for long-span beams, lintels and load-bearing members where sawn timber can’t deliver the required strength or straightness. The F17 grade provides higher bending strength and stiffness than F11, suiting demanding structural applications, and H2S treatment protects against borers and termites in enclosed above-ground conditions.

At this depth, 400 x 45 LVL F17 H2S is typically specified by an engineer for feature beams, wide door and window openings, and long clear spans in both residential and light commercial builds. Confirm exact span and loading requirements against your engineering documentation before ordering.
