This document is a technical specification and installation drawing for a 20 x 20 Heavy Duty Sluice Gate manufactured by Hydro Gate Corporation, located in Commerce City, Colorado. The drawing serves as an order specification for a single gate unit with installation drawing number M0549001.

The gate is constructed of etched stainless steel with blue baked-on enamel and measures 3 7/8 inches in width and 1 3/4 inches in height. Material specifications indicate the gate assembly uses cast iron naval bronze for the frame and slide bearing races, manganese bronze for various wedge blocks and accessories, and stainless steel fasteners. The stem and accessories utilize stainless steel components with manganese bronze elements. The lift assembly incorporates cast iron pedestals and housing with manganese bronze nuts and naval bronze stop nuts. Stem guides and wall brackets are fabricated from cast iron, with carbon steel and tin bronze used for base plate components. Coating specifications require a near-white blast clean finish per SSPC-SP10 followed by application of TNE/MEC 46H-413 H-Build TENEW-TAR in black for a dry film thickness of 16-20 mils on the gate, stem guides, and wall bracket. A rock-hard poly-enamel #649 in medium gray is applied to the lift and base plate stem guide components at 1.5-1.8 mils dry film thickness. The technical drawing includes detailed dimensional specifications, assembly configurations, and comprehensive notes regarding seating surfaces, clearances, and material specifications for installation and alignment.
