CONSTRUCTION
The laminate Corrosion Barrier is the Inner Surface and Interior Layer combined. The glass content of the Corrosion barrier shall be 27% ± 5% by weight. The most important feature to any fiberglass tank in the corrosion industry is the corrosion barrier of the tank. Each tank Laybond manufactures is built using a male mold to help ensure a smooth, resin rich internal finish to aid in corrosion resistance.
Economy Resin System
Isophthalic polyester resin throughout the laminate.
Standard Resin System
Our "STANDARD" resin system consists of Premium grade Vinyl ester resin in both the Inner Surface and Interior Layer. Isophthalic polyester resin is used in the Structural Layer and Outside Surface.
Premium Resin System
Premium grade Vinyl ester resin throughout the laminate.

DESIGN FEATURES
TANK BOTTOMS
Flat & Sloped - The majority of our Flat and Sloped Bottom tanks use a unitized one-piece bottom to sidewall construction without a seam for greater structural strength. However, we don't stop there. The tank bottom corners include a knuckle radius for maximum resistance against hydrostatic pressures, and corners are easier to clean to help eliminate product contamination.
CONE & DISHED
The majority of our Dished Bottom tanks also use a unitized one-piece bottom to sidewall construction without a seam for greater structural strength and ease of cleaning. We utilize both FRP and Steel support structures, overlaying the steel support ring exterior with fiberglass for added resistance against chemical attack. The full circumference support helps eliminate uneven stresses on the tank sidewall.
TANK TOPS
Closed : - Laybond Tank Dome and Flat Top Heads come standard with our 20" or 24" loose cover top manhole with grab handle for convenient opening.
OPEN : - Our Open Top tanks come standard with a 90° rim flange, with the option of a one, two or three piece cover. The 90° rim also allows for easy mounting of mixer rails, when required. As a cost saving alternative, a Type II rim is offered when a cover or rails are not required.
Note :
All Laybond Tank 90° rims are formed by means of hand lay-up to the tank sidewall on a platen table to ensure uniformity
Fittings
Laybond Tank flanged nozzles are made via the hand lay-up process as a standard which offers superior strength and corrosion resistance. Conical and plate gusseting is also offered, where added strength is required.Accessories
Our standard insulated tanks come equipped with a reinforced fiberglass outer protective shell for protection of insulation against damage from mechanical impact and environmental degradation. We also offer a replaceable type heat panel for tanks that need to maintain a given product temperature. Heat panels help eliminate the high cost associated with repair or replacement of wire heating systems which require complete removal of the tank insulation, and later re-insulation of tank after repair or replacement.Downloads
