«Nevsky Composite LLC» is one of the leading manufacturers of wood-polymer composite (WPC) products in Saint Petersburg.

Our product range includes:

  • decking
  • siding
  • lags of various modifications
  • decorative fence
  • interior and vestibule doors
  • doors for medical institutions, kindergartens and schools.

All products are produced on high-tech extrusion equipment from leading manufacturers such as Mikrosan makina, Jwell, etc.

The automated line, which was launched by employees of the above mentioned companies, ensures an uninterrupted technological cycle.

The selection and preparation of raw materials for production is made according to the strictest quality standards.

The team of professionals, including the extrusion line operator, mixer operator, operator and assistant operator of the raw material preparation and mixing shop, regularly improves their skills. Each specialist is a true master of their craft.

The products of the «Nevsky Composite LLC» plant can be called unique and innovative - in terms of their characteristics, they are in many ways superior to all the world known analogues.


In production, we use both domestic raw materials - wood flour (produced by ourselves), marble chalk, PVC components, and materials from foreign manufacturers - stabilizers, pigments, modifiers.

Thanks to the well-coordinated work of our specialists, we were able to develop a composite formula with a low cost of initial raw materials, which allowed us to make the final product affordable to our consumers.

But the price of our products is surely not the only way how our customers are going to benefit from doing business with us. The moisture absorption coefficient of our products is only 1.5% at a rate of 5%, and the material can withstand high mechanical loads.


Wood-polymer composite is an analog of real wood, but it has the following important advantages:

  • Waterproof
  • Fireproof
  • Does not rot and does not require treatment
  • Resistant to abrasion
  • Not subject to the formation of fungi and mold
  • Retains the geometry and color during the whole period of operation
  • Long-lasting (service life of at least 20 years)
  • The texture and smell completely resembles natural wood
  • Does not contain phenol formaldehyde resins


wood flour with a fraction of 0.5-2 mm

polymer (we use PVC-polyvinyl chloride)

a complex of special additives (modifiers, additives, flame retardants).


Wood-polymer composite is obtained by mixing polymer and wood flour or fine wood fraction to a homogeneous mass. The result is a material that is very similar to products made of natural wood, not only in appearance, but also in touch and smell.

Due to its unique properties, WPC is referred to as "liquid wood".


WPC technology makes it possible to produce complete sets of doors, including door leaves, box parts and telescopic mouldings (platbands and finishing elements).

Then all the parts are machined and lined with veneer or films. This is the least labor-intensive way to produce doors.

The advantages of such doors are obvious:

  • Have the texture of natural wood
  • Do not scratch (vandal-proof)
  • Do not warp

All products have all the necessary quality certificates and test reports.
