FRP flanges and blind can be classified into two main categories compression molded and pultruded. Compression molded FRP flanges and blind are made by placing layers of fiber reinforcement and resin in a mold and then compressing them under heat and pressure. Pultruded FRP flanges and blind, on the other hand, are produced by pulling a continuous fiber strand through a resin bath and then shaping it into the desired form.

The grp stack is a data structure used by the kernel to keep track of a process's set of gids. Unlike the User ID (UID), which typically remains constant for a process throughout its lifetime, the gids can change dynamically as a process executes. This mechanism allows for flexible permission management, where processes can take on different levels of access based on their current effective or supplementary gids.
