  Steel PreparationSteel Preparation: After material is fabricated, Natural Structures abrasive blast cleans the steel surface to NACE No.2/SSPC-SP10 or near white with a 1.5 mil surface profile.

The material then advances to the phosphate wash system. This is designed for the removal of any grease, dust, flash rust, or any other light foreign substance that prevents the polyester powder from adhering to the surface being coated. Natural Structures ecologically friendly process utilizes a five step system into 3 steps: #1 rinse; #2 cleaning & phosphate; #3 final rinse hereby saving precious water & energy resources.

  Hot Dip GalvanizedHot Dip Galvanizing: Available after fabrication & in accordance to specification section ASTM A-123. Powder coating is available for hot dip galvanized surfaces.
  Pressure TreatedLumber Pressure Treatment: Lumber is Wolmanized® Natural Select® Copper Boron Azul (CBA) Cedar Tone color, vacuum pressure treated to refusal. Pressure treatment is used for wood members against fungal decay and termites in accordance to the American Wood Preservers Association (AWPA) Commodity Standards C1-100 and in the processing & treatment standard of the Use Category System (USE) after fabrication.

  Stain/SealerColored Stain: Olympic® wood preservative. It provides a water guard and water repellant. It is also rot, decay & mildew resistant while providing ultra-violet sun block protection against sun damage.
Clear Sealer: Wolman® RainCoat® 100% clear oil base water repellant designed to protect wood against water damage & resist mildew. It is colorless and imparts a clear oiled look allowing the woods original color & character to show through and gray naturally from ultra-violet exposure. RainCoat® is fortified with mildewcide that resists mildew growth. It prevents water penetration, thereby minimizing wood cracking, checking, and preventing major damage such as splitting & warpage. It is recommended for immediate applications of untreated or pressure treated lumber.
  Natur-Kote Undercoat Natur-Kote Primer: is a single part fusion bonded epoxy undercoating (primer). It is ideal for its resistance to wastewater, corrosive soils, hydrocarbons & seawater. It will not sag, cold flow or become soft. It is an excellent option for areas needing an extra protection layer. Minimum thickness: 3-4 mils.
  Anti-Graffiti Powder CoatAnti-Graffiti Powder Coat: The anti-graffiti powder coat is an exterior graffiti resistant aliphatic urethane polyester clear coat. It is applied over the standard color. To remove graffiti use 100% Isopropyl Alcohol (IPA), this will remove most black permanent marker. This is an excellent option for high vandalism areas. Minimum thickness: 2-4 mils.
