Hatch #210

Hatches can be made from the following materials:
•  A36 mild (carbon) steel with these finishes:

• Shop cleaned (SP3) and red-oxide primed. This is our standard finish.
• Sandblasted to white metal (SP10) and primed with an inorganic zinc primer. Cathacoat 302 (also known as Devoe 302) is the primary inorganic zinc primer we use. This is a premium finish available at an additional cost.
• Specialized paint / primer finishes are available at an additional cost. Custom paints may significantly increase the product price, since the paint systems cannot be re-used on other jobs.
• Galvanizing is another premium finish available at an additional cost. This finish option also adds at least two weeks to the lead time.

 •  304 Stainless Steel 

 •  316 Stainless Steel

Yoke Assembly:

• Oil cargo hatches from other manufacturers have a very similar appearance to Cen-Tex Oil Cargo Hatches. Replacement parts for Cen-Tex Oil Cargo Hatches will not work for oil cargo hatches made by other manufacturers. If you need replacement parts for a yoke assembly, our sales staff will need to review photos to make sure that our replacement parts will work for your hatch.

•30 +/- 5 Durometer extruded neoprene, 3/4” x 1-3/4”

 • Computing gasket length 

Spacing for Hatch Cover Swing:

• To allow the hatch cover to open to 90 degrees, the coaming must be a minimum of 5” away from the nearest bulkhead

ABS Type Approval / Classing Agency Approval:
• All doors are built to standards generally accepted by ABS, USCG, and other classing agencies. 

• Doors do NOT carry ABS “Type” approval. For further explanation, click here.

• Drawings and release letters are available for submission for classing agency review.

• It is the responsibility of the customer to verify which certification requirements (i.e. ABS, USCG, DNV, SOLAS) apply to their vessel, and to check with their local governing agency as to the requirements for certifications for all of the items quoted, based on the use for each item on the vessel, and the location of each item as installed on the vessel. Depending on the requirements of the governing agency, additional testing at the manufacturing plant may be required. A separate fee will be charged for any testing.

• Doors conform to C-class fire rating - they are made of non-combustible materials, however, they are NOT designed or certified to resist the passage of fire from one space to another.
