How To Measure and Cut-To-Size Policy | Close it

Cut-To-Size Items are Non-Returnable!

As per our Shipping and Returns Policy, custom cuts and fabricated parts are non-returnable. If you need an over- or undersized item, note it under \"Comments\" during Checkout. Cut-to-size orders have an acceptable cut tolerance of 1/8" (0.125"), so clarify if the adjustment is to be made on the (+) or (-) side of the saw blade. Please review our full return and shipping policy here.

Measure Twice, Cut Once

Since custom cuts and fabricated parts are non-refundable, be very careful while measuring your dimensions. As each cut is nominal, even the slightest miscalculation could be costly.

How to Use a Measuring Tape

Extend your tape measure several inches to find the 1 and 2 inch markers. In between the inch markers you’ll find 16 equally spaced tick marks.

Measure by counting the increments beyond the nearest inch. As the increments decrease, so does the length of the mark. For example, 1/2\" has a bigger mark than 1/4\" which has a bigger mark than 1/8\". The smallest mark follows at 1/16\". Please be aware that some measuring tapes may have even smaller increments.

Features of a Measuring Tape: Sliding End Hook

The sliding end hook is designed for two different types of measurements. An outside measurement (where the hook of the tape hangs over an edge), requires the hook to slide out a bit to account for the thickness of the material. When making an inside measurement (where the hook will push up against a surface), the clip slides in, again, accounting for its thickness. The measuring tape self-adjusts to guarantee an accurate measurement (as far as the tape is concerned).

Description

Marine Board HDPE (or High Density Polyethylene) is a lightweight, tough thermoplastic, environmentally stabilized to withstand the most challenging marine environments.

Marine Board HDPE is a superior alternative to wood at a very economical price. It's resistant to salt water, a wide range of chemicals and UV exposure, and unlike other alternatives, Marine Board doesn't splinter, crack, delaminate, rot, swell or absorb water. Even under heavy foot traffic on yacht decks, Marine Board remains virtually maintenance free.

Interstate Plastics also carries King Starboard® HDPE Marine Board, the industry standard for extreme outdoor weather performance. Interstate Plastics provides Marine Board as a more economical version of Starboard®, without sacrificing material specifications or performance, and also offers varying grades of Marine Board plastic including King StarBoard®, King StarBoard® A/S, King StarBoard® XL, and King Starlite® XL Utility.

Wear Resistance
With a self-lubricating formula and a high sliding resistance alongside excellent long-term durability and weather resistance, Marine Board HDPE is an ideal marine plastic for a variety of applications including replacing wood, metal or laminate walkways, hatches, walkways, cabinetry and countertops as well as ship and boat components regularly exposed to harsh outdoor environments.

Textured Surface
In addition to its resistance to marine and other outdoor conditions, Marine Board has a decorative, textured surface that does not show wear, dirt or scratches.

Salt Water and Moisture Resistances
HDPE Marine Board is a lightweight and extremely tough, chemically resistant plastic. It does not absorb water and has a good sliding abrasion resistance in addition to a specialized self-lubrication. Unlike many other marine-based materials, Marine Board is environmentally stabilized to resist salt water, and will not rot or degrade.
