MATERIAL SCIENCE

Green Bay Decking is committed to science and continuous improvement from our products to our manufacturing methods to our quality control processes. The quality of the raw materials directly affects the quality of the products.

Our material formulation is proven. We have decks that have been in place and exposed to the elements for 16 years in many different climates. We believe in proactive research and development, to constantly be testing new technologies, and adopting those that can benefit our products, builders, and homeowners. 

HOW IT IS MADE

SCIENCE & FORMULATION

Our material science combines:

High density polyethylene (HDPE)
Rice Hulls
Biodac
Colorant
Antioxidant, Antifungal, Other

Click through the tabs below to learn more about each ingredient.

High Density Polyethylene (HDPE)

Virgin material – free of contaminants

Highly resistant to chemical attack

Density (0.960) contributes to density of decking

Density contributes to resistance from internal attack

Readily available in the required quality specs

Strong

Chemically resistant

Non-toxic

More consistent product

Better control of properties

Less variation

Clean (No commingling or dirt)

Rice Hulls:

High silica content (sand or glass like)

Natural protectant qualities

Provides strength and stiffness attributes

Rapidly renewable resource – Environmentally friendly

Biodac:

Reclaimed paper-making by-product

Environmentally sustainable

Very high density (1.32) contributes to density of our product

Contains calcium carbonate and clay – Inert materials that contribute to stable product

Tannins and lignins stripped from by-product to help resist staining and fading

Colorant:

Iron oxide base provides a stable color quality

Helps resist fade

Work with renowned colorant suppliers

Added during board extrusion process to provide production control

Anti-oxidant:

Serves a dual purpose in manufacture and board service life

Provides resistance to thermal destruction of plastic in the manufacturing process

Acts like an ultra-violet (UV) inhibitor to resist attack and breakage of the plastic chain

Anti-fungal:

Helps prevent the growth of fungal material within the decking

Lubricant:

Serves a dual purpose in manufacture and board service

Mates with iron oxide based colorants to migrate in and out to create surface finish

Quality Control Procedures

Materials:

All incoming raw materials are submitted to QC testing and validation.

If it does not pass, it is rejected and not used.

There is no “good enough” for Green Bay Decking products. 

The quality of the materials directly affects the quality of the products.
