By far the most widely used material for building the worlds infrastructure and industries, it is used to fabricate everything from sewing needles to oil tankers. In addition, the tools required to build and manufacture such articles are Handbook of Comparative Handbook World Steel writing such a handbook. There were many steel standards from around the world that were new to me, which created far too many surprises and delays in completing this book. Comparing steel standards is not an exact science, so the biggest challenge of preparing such a book was deciding on the "rules

If you spend any time in the kitchen or outdoors, you'll understand the value of having a
Grading Rule, except for special products such as scaffold planks. Grade rules for other sizes, such as nominal 5 in. (standard 114 mm) or larger structural timbers may vary between rules writing agencies or species. The National Grading Rule establishes the lumber classifica tions and grade names for visually stress graded dimensionDetermining Scantlings According to the ABS RuleThe ABS MPY has proven to be an excellent all around rule, although it has now effectively been superseded by the 2016 ABS Yachts Rule (see below). 2016 ABS Steel Vessels Rule (SV) Applies to steel commercial vessels up to 295 feet in length (90m). Specified by the US CFR for use on steel yachts carrying passengers for hire, whether power or sail.
