Stiff, Straight LVL Engineered for Formwork
Formwork LVL E12 H2S is laminated veneer lumber made from many thin, pre-graded pine veneers bonded under factory conditions into straight, uniform members. Its E12 stress grade gives it greater stiffness than standard E10 framing LVL — important for formwork, where bearers and joists must resist deflection under the weight of wet concrete to hold accurate slab levels and finishes. Its straightness and consistency make formwork faster to set out and more predictable to strip and re-use. The 'H2S' designation means a glueline termite treatment is infused into the adhesive during manufacture, protecting the whole cross-section so cuts and drill holes need no re-treatment. H2S is for dry, above-ground use south of the Tropic of Capricorn; formwork LVL should be protected, cleaned and stored well between pours to maximise its working life.

Longer bearer and joist runs in formwork.
General engineered formwork where consistency and re-use matter.
Working With Formwork LVL E12 H2S
Formwork LVL E12 H2S can be cut, drilled and fixed with standard timber tools and fasteners. Set out bearers and joists to the formwork design and the manufacturer’s data; the E12 grade describes stiffness, but the spacing and member size for a given load must follow the formwork design and a competent person or engineer. Support, brace and tie formwork in accordance with safe-work and design requirements. To get the most cycles from formwork LVL, protect it from damage, clean it down after each pour, avoid prolonged saturation and store it flat, supported and under cover between uses. Inspect members for damage before re-use and remove any that are compromised.

The H2S glueline treatment infuses termiticide into the adhesive during manufacture, protecting the entire cross-section against termites and borers, with no need to re-treat cuts or drill holes on site. This through-section protection suits formwork members that are repeatedly cut and drilled. H2S is for dry, above-ground use and may only be used south of the Tropic of Capricorn; it is not a weatherproofing treatment, so formwork LVL should be protected from prolonged wetting and stored well between pours. For applications requiring exterior, above-ground weather exposure, an H3-treated product is required — talk to our team about the right option.

Getting the most out of Formwork LVL E12 H2S starts with specifying it correctly. The stress grade tells you the stiffness, and the treatment tells you where it can be used, but the actual member size for a given load and span comes from the manufacturer’s published span tables and design information — and, for primary structural members, from your project engineer or building designer. We can supply the exact sizes, grades, treatments and lengths called up on your plans or engineering documentation, so the simplest approach is to send us your schedule and let us match the product to it. Where it helps, we will also point you to the relevant span tables and technical literature. When you order, it pays to confirm the depth, thickness, grade, treatment and length of every member, plus the quantities, so the delivery arrives complete and ready to build with minimal waste. If you are weighing up grades or treatments — for example, whether a job calls for E10 or stiffer E14, or H2S versus an exterior H3 product — our team is happy to talk it through and help you specify the right member for the application, the location and the budget.

Formwork bearers and joists must resist deflection under the weight of wet concrete to hold accurate slab levels, so the stiffer E12 grade is well suited to the job. Always design spacing and member sizes to the formwork design and manufacturer’s data.
