Flanges are flat bar profiles that are fixed to the sides of a plate, usually for reinforcement or as a mounting surface. During the production process, the way each flat bar is connected to the plate is carefully analyzed to ensure structural integrity and proper fit.
Let's break down the flat bar specification and additional placement codes you mentioned In the following figure 1.
Flat Bar Specification "FB80x5 L345":
FB stands for Flat Bar.
80x5 indicates the dimensions of the flat bar:
80 is the width in millimeters.
5 is the thickness in millimeters.
L345 denotes the length of the flat bar, which is 345 millimeters.
Additional flange placement codes according to Figure 1 are:
<25 or <49: This code provides specific positioning information about the flat bar:
The code "25/49" indicates the position of the web on the flange, measured in millimeters. Specifically, this measurement defines the distance from the edge of the flange to where the web begins.
A75 or 105: This code specifies an angle (A) related to the flat bar:
The code "A75/A105" indicates the angular range in degrees at the side of the plate where this corresponding number is marked.
