Plantation Grown. All veneers used in the manufacture of NelsonPine LVLare peeled from sustainable plantation grown Pinus Radiata logs grown in theNelson district forests.
EASI FORM is manufactured from NelsonPine LVLand is intended for use as concrete formwork, joists,bearers, Walers, Soldiers and Supports. EASI FORMis strong, light, straight and uniform which will reduceforming costs and improve the quality of concretefinish.
EASI FORM has chamfered edges for ease ofhandling and a water repellent paint finish.

STORAGE AND HANDLING
NelsonPine LVL expands in thickness and depthwhen allowed to get wet. To ensure the full benefitsof NelsonPine LVL as a dry, straight and true materialare available at the time of installation, the followingrecommendations regarding storage are made:
1. NelsonPine LVL is kept dry during storage andtransport
2. Stored under a ventilated cover with fillets placedbetween each layer
3. Stacked clear of the ground on at least threeevenly spaced bearers
4. Bearers and fillets to be placed vertically in lineand support NelsonPine LVL evenly and flat
5. Avoid mechanical damage during handling
6. Re-seal cut edges with a water repellent paint
Note for joist and bearer tables
1. The design for the joist and bearer tables includea 4kPa allowance for stacked materials inaccordance with AS3610. Where this allowancecan be reduced, the spans given above maybeincreased with advice from the formwork designer.
2. The deflections of the joists and bearers havebeen limited to those required for a Class 3 finish(the greater of span/270 and 3mm). Since thefinish quality is dependent on a number of otherfactors including formface quality, supportdeformations and the accuracy of the set up, aclass 3 finish cannot be guaranteed.
3. For multiple spans, the design has assumed themost conservative of 3 and 2 spans and that allspans are of equal length and equally loaded.
4. The design has assumed that the joists arecontinually restrained by the sheeting and thebearers are restrained by the joists.
5. To satisfy the bearing requirements of the timber,the thickness of the bearer must be equal to orgreater than the thickness of the joists it issupporting.
6. Spans values may be interpolated for intermediateslab thicknesses.

Notes for vertical forms
1. The design of the vertical forms is based on ahydrostatic pressure distribution.
2. Deflections of the soldiers and walers have beenlimited to the greater of span/270 and 3mm asrequired for a class 3 finish. Since the finish qualityis dependent on a number of factors includingthe formface used and the accuracy of the setup, a class 3 finish cannot be guaranteed.
3. Tie bolt holes are not to be bored through any ofthe soldier or waler members.
4. The maximum distance from the top of the formto the nearest tie rod must be a maximum of650mm.
5. The forms are not suitable for grout injectedconcrete, concrete pumped from below, deep re-vibration or external vibration of the concrete.
