PRODUCTS
Exterior Birch Plywood(WBP) and Film Faced Plywood(FF) is a high-quality construction material with high durability and moisture resistance.
Based on the direction of the grain of the veneer layers, plywood is divided into 2 types: cross grain(4×8 ft format) and long grain (8×4 ft format).
– Cross grain plywood: in this type of plywood, the layers of wood are perpendicular to the direction of each other. This means that the grain direction of the outer layers will be oriented along the short side of the plywood sheet;
– Long grain plywood: in this case, the layers of wood are oriented parallel to the long side of the plywood sheet.
Plywood with long veneer grains is used where flexibility is required, and with transverse veneers – where high bending rigidity is required.
Also, plywood with long grains is very popular in the furniture industry due to the ability to produce parts with long grains of a larger size than with cross grains.
We offer both cross and long grain large-format plywood in the following sizes: 1220*2440/1250*2500 (cross grain);
And 2440*1220/2500*1250 (long grain).
In the production of our WBP and FF plywood, an adhesive of a unique formulation is used, prepared on the basis of components from leading manufacturers in the chemical industry, which allows us to achieve maximum quality indicators.
This ensures that WBP plywood meets GOST 3916.1-2018 and GOST 53920-2010 (for FF) in terms of strength and moisture resistance, and what is very important, the products have consistently high quality, controlled at all stages of production, as well as high environmental friendliness.

FILM FACED BIRCH PLYWOOD FF and FW ("ANTISLIP" or “HEXA”)
Made from specially prepared high quality WBP birch plywood by applying phenolic film to the surface. Thus, the plywood receives constant protection from moisture and external mechanical wear. The laminated plywood produced by GROUP DELTA INVESTMENTS has two types of anti-slip coating: the classic “anti-slip” coating or the “HEXA” texture, reminiscent of a honeycomb. Both types of these coatings, in addition to excellent anti-slip properties, have increased wear resistance, confirmed by laboratory tests. “HEXA” also has increased water-repellent ability compared to the classic coating, since the integrity of the phenolic film is not compromised during production. The coating also makes cleaning much easier and has a very attractive appearance. In addition to laminated plywood with anti-slip coating, we produce plywood with a smooth coating on both sides(FF), which is often used in the construction and other industries.
RAW MATERIALS
The lower part of the trunk of a birch – raw materials for the production of plywood. This should be a very high quality timber without knots with a diameter of from 200 to 350 mm and a length of 5-6 meters. It is sawn on “logs” of 1300mm and then the RAUTE Smart peel 4/5 is making the veneer with thickness of 1,5 mm.
ExteriorWBP plywood is used in the following areas:
-
Interior and exterior trimming of premises of different purposes. Plywood WBP is a stuff of higher durability and water-resistance, and due to that is used in construction, especially in rooms with high moisture.
-
Sheathing. In construction the WBP plywood is widely used as the material for sheathing construction for pouring with concrete. In wall construction and roofing such a kind of plywood is also very popular.
-
Machinery industry, shipbuilding, aircraft building, rail craft building. Plywood WBP is indispensable for making of thermic panels and body constructions with heat-isolated materials, septa and bulkheads in shipbuilding and other fields of transport engineering.
-
Manufacturing of package and components. Exterior plywood is used for boxes, pallets, trays and other items for logistics.
-
Fabrication of big-sized outdoor billboards. WBP plywood is highly called-for in advertising field due to its resistance against atmospheric forcing
Film Faced HEXA Plywood is used in the following areas:
-
Production of concrete forms in cast-in-place construction
-
Construction of playgrounds
-
Manufacturing of decking in scaffolding
-
Manufacturing of floors in vans and trucks
-
Manufacturing of furniture, retailing and warehousing equipment
-
and much more…
"GROUP DELTA INVESTMENTS" LLC has been specializing in producing and wholesales of the plywood, and has taken during this time a reputation of a reliable supplier of birch WBP and HEXA plywood and also of bakelized plywood to export markets and within Russia.
