TECHNICAL 00 · INDEX
The technical library: how to specify a frame so that it can be built, shipped and inspected.
Twenty-four guides written for the person who has to sign the drawing and clear the container. Each one ends with the inputs we need and the assumptions we refuse to make for you.

These pages exist because most frame disputes are not about quality — they are about an assumption nobody wrote down. A purlin spacing that was never stated, a snow load taken from a neighbouring country, a coating class that meant something different to the inspector. Write the assumption down and the dispute disappears.
