Birchply™ - Deck 350 Formwork Shuttering Plywood
An ultimate in performance and durability
Deck 350 Birchply™ is a special film faced plywood with a grid pattern intended for deck formwork. It comes with 25, 50, and 100 mm grid patterns. This simplifies plywood laying-out and cutting, and reduces labor costs at the construction site. The pattern also can be used as the template for rebar placement.
Deck 350 Birchply™ edges are coated with special acrylate-based waterborne Finnish-made paint with low water permeability. Deck 350 Birchply™ surface is smooth, and coated with German-made wear resistant material (wearing capacity is 350 Taber test rotations).
Deck 350 Birchply™ Film face Birch Plywood is ultimate in Plywood having excellent physical and mechanical properties. The rigid laminated surface not only prevents moisture absorption but also ensures excellent abrasion resistance in aggressive conditions and smooth finish to concrete formwork.
Deck 350 Birchply™ Birch Plywood has been designed to suit any and every application needs of construction industry where durability, versatility, high bending strength, rigidity, stability, accuracy and tolerance to humidity parameters of performance value are critical.
Patented Technology:
* Production process for plywood with a grid pattern is patented (registered in the National Register of Utility Models of the Russian Federation as of 20.01.15, RF Patent number 150519).

Effect of humidity and moisture
- Wood veneer is a living material and is subject to moisture movement according to surrounding conditions, which affects the flatness of panels. It is important to condition the panels to reach a moisture content near to the equilibrium of their permanent environment.
- Like other wood-based panel products, Birch Plywood is also hygroscopic and its dimensions change in response to a change in humidity. A change of 1% in moisture content typically increases or decreases the length, width and thickness by 1% in dimensions and thickness. It is therefore desired that the edges are sealed with a suitable acrylic paint to prevent and/or control ingress of moisture and humidity and consequent swell in thickness and expansion in dimensions.
- The recommended stocking conditions are 20°C and a RH of air of about 60%.
Storage conditions:
