How do we ensure that we achieve thickness consistency for British Standard Rolled Lead? We have a gauge on our Rolling Mills which measures the thickness of the Lead sheet when it is being rolled throughout the whole process. We also gauge it by hand as well. We double check and triple check all the time.

Rolling Process Definition. The rolling process is a metalworking operation in which metal strips pass through a set of rollers to reduce sheet thickness and achieve uniform thickness throughout the sheet. The sheet is deformed along the linear axis. Typically after the rolling, metal sheets go through annealing which is done under a closed environment of nitrogen.

Lead sheet is formed by passing a slab of refined lead back and forth on a rolling mill between closing rollers, to a predetermined thickness. The sheet is then slit to width and cut to length for final packing and distribution. Such is the consistency of the process that lead sheet will not vary in thickness by more than +/-5% at any given point.

For many years milled lead sheet is the method by which the majority of lead sheet has been manufactured. It has a shorter life of 100+ years, as it is thinner than cast lead. It is made by running a slab of lead through a rolling mill several times, until a sheet of the correct thickness is achieved.

Flat rolling – the finished product is a sheet. Profile rolling – the finished product is a bar or rod. The process always starts with hot rolling. Hot rolling refers to the process of rolling steel at a temperature typically above 900 °C, greater than its recrystallisation temperature.
Around 1606: The most failed technique of sheet metal is invented. Puddling involves heating up the cast iron to liquefy material in reverberation furnaces, but only used the flame, which results in an insufficient amount of power. 1615: The first industrial plant produces lead and tin plates. 1682: A cold rolling mill is found in England.
Sheet iron was first known to have been manufactured here by the Revolutionary War financier, Robert Morris, who had a rolling mill near Trenton, New Jersey. At his mill Morris produced the roof of his own Philadelphia mansion, which he started in 1794. The architect Benjamin H. Latrobe used sheet iron to replace the roof on Princeton's "Nassau ...
The real turning point in the sheet metal production took place with the introduction of the rolling mill. The first known design of a rolling mill dates back no less than to Leonardo who in one of his drawings, dated 1480 (Figure 2), describes for the first time the possibility of "making a material pass" between two cylindrical rollers ...
