Hot rolled structural steelwork leaves the last rolling pass at a temperature of about 1000°C. As it cools, the surface reacts with oxygen in the atmosphere to produce mill scale. This is a complex oxide which appears as a blue-grey tenacious scale completely covering the surface.
Mill scale, dirt, laser scale, rust, heat-treat scale, grease, and dust interfere with paint and coatings' adhesion to structural steel and must be removed before steel members can be coated. What are structural steel fabricators doing about surface preparation, and what options are available? Surface preparation can run from simple chemical cleaning to abrasion …

A type of cold-rolling mill, the tandem mill imparts greater strength, a uniform and smoother surface, and reduced thickness to the steel sheet. Unlike the original single-stand mills, a tandem mill rolls steel through a series of rolls (generally three to five in a row) to achieve a desired thickness and surface quality. Tantalum 5

Unlike the post mill where you had to move the entire structure to orient the mill, only the cap had to be moved in the tower mill. Both the tower and post mills were originally designed to be manually oriented into the wind by pushing a lever located on the back of the mill. In 1745, Edmund Lee invented the windmill fan tail, which was mounted ...

Structural Angle is a steel bar that has an L-shaped cross section. It is a piece of structural iron or steel in the form of a 90 degree angle. It is ideal for all structural applications, general fabrication and repairs. This item can have equal sized legs (or flanges); this is typically known as equal leg angle.
It is a piece of structural iron or steel in the form of a 90 degree angle. It is ideal for all structural applications, general fabrication and repairs.
