CF: CHEMICAL PROOF (standard colour is dark gray) is a vinyl ester system specifically engineered to provide premium service in highly corrosive environments. It utilizes an advanced resin system which delivers outstanding resistance to a wide range of harsh corrosive environments ranging from acidic to caustic, plus a high degree
of solvent resistance. It has a Class I flame spread rating of 25 or less according to the ASTM E-84 Tunnel Test Method.
CR+: CHEMICAL PROOF PLUS (standard colour is black). This is our only EF.R.P™ Grating to offer a flame spread rating of 10 or less on ASTM E-84 Tunnel Test. It has excellent acid and caustic resistance.
IF: INDUSTRIAL GRADE (standard colour is light gray). This is a premium corrosion resistant isophthalic resin system selected for outstanding acid resistance. It has moderate resistance to caustic and solvent environments. It has a Class I ASTM E-84 Tunnel Test flame spread rating of 25 or less. It is more economical than types CF and CR+.
FF: FOOD GRADE (standard colour is safety yellow). Agriculture Canada approved (all ingredients have been USDA approved) to meet corrosive conditions commonly found in meat production, food processing, bottling and brewing applications. Made with isophthalic polyester. Flame spread rating is 30 or less.
AF: ARCHITECTURAL GRADE FIRE RETARDANT (standard colour is light gray). This is a resin system designed for mildly corrosive environments. Best suited to replace metal gratings that require maintenance to maintain an aesthetically pleasing appearance. It has a Class 1, ASTM E-84 Tunnel Test flame spread rating of 25 or less for indoor use. It is more economical than type IF.
AN: ARCHITECTURAL GRADE (standard colour is green). Similar resin system as type AF but is not fire retardant or flame spread rated. More economical than AF.
Grating Selection Process
1. Select the proper bar spacing and height to meet your load requirements.
2. Select the proper resin to meet your environmental requirements.
3. Select the proper panel size to meet your requirement.
4. Determine if you want grit top or plain top.
Deflection to Span Ratios
• For a resilient, non-fatiguing, comfortable feel use the STANDARD deflection to span ratio of 1: 120.
• For an elevated installation, where a solid feeling is desired, use a deflection to span ratio of 1: 180 (NBC-85). A deflection to span ratio greater than 1:100 (1%) is not recommended. Do not exceed .5″ (13mm).
Panel Selection
• Determine the type of loading: concentrated or uniform.
• Estimate the load and determine the span.
• Decide what maximum deflection is appropriate: solid, standard or 1 %.
• Enter the appropriate l” (25mm) table. If the deflection is less than the maximum selected, choose the l” thickness. It is more economical than 1.5″ thick panels.
• If the deflection or span is too great for 1″ thick panels, select 1.5″ thick FRP Grating and design your support system for the appropriate span.
• Select the resin system.

• Panels are designed to be supported on all sides.
• Use end clips if panel ends cannot be supported.
