| This Australite tektite is an example of rare tektites which have flanges around their margins. |
| Finally, they lay mesh over the flanges, position it above the plywood forms, and cast concrete on top. |
| Often, reflective insulation materials have flanges that are to be stapled to joists in attics or floors, or to wall studs. |
| Further forward, the wreck is flat to the seabed, just a few curved plates rising above the sand, some with flanges and valves projecting. |
| However, at the building's lower levels, the flanges are pointed inward to prevent accidental damage. |
| The base plate may include flanges disposed along the outer periphery of the base plate. |
