Preventing corrosion
Most structures that rust too fast were not badly protected: they were badly designed. The traps, one by one.
Technical guide
Choosing a steel tube
At equal mass, a tube is seven times stiffer than a solid round. Here is why, and how to calculate the weight of all three tube families.
Product guide
Steel angles
The most versatile section in metalwork, and the one most often chosen by eye. Here are the common sizes and their real weights.
Technical guide
Sizing welded mesh
Two diameters, two spacings, one format: everything else follows. Full method, with a worked example on a 6 × 2 m panel.
Product guide
Black or galvanised sheet
Galvanised is not "black sheet, but better". They are two products with opposite constraints, particularly when welding and cutting.
Standards & uses
Galvanised wire gauges
A gauge number is not a measurement. Here is why ordering "JP12" invites a misunderstanding, and what to specify instead.
Standards & uses
High-yield rebar
A Ø12 bar weighs 0.888 kg/m. Where that number comes from, what the ribs are for, and what to check on unloading.
Product guide
Choosing a beam
Five profile families, five structural logics. Understanding which works in bending, which in compression, and why confusing them is expensive.
Technical guide
Steel sheet weight
