The Square Hollow Section Changed How Steel Buildings Were Built

The Iron Age symbolized the origin of steel. Steel is a mixture of several metals, but most of it is iron. Iron is second to steel which is harder and stronger. In 1856, there was a breakthrough in steel manufacturing, with the development of the Bessemer process, which used oxygen to both harden and strengthen steel.

Maintaining the integrity of structures requires building materials that contribute to both strength and flexibility.

History of Tubular Steel

The properties of tubular shapes have been known since ancient times. Historically, in the late 1900s, some bridges were built on tubular columns made from riveted rolled plates which led to the production of seamless welded circle hollow sections.

After the Second World War, hollow sections of steel were welded together using perfected welding and steel rolling practices.

Cool Gifts To Give This Year

I work in the technical field so I’m surrounded by techno-geeks on a daily basis. As with most electronics ordered, there’s no paperwork on any of it. I can figure out most of it, but the motor has two unlabeled soldering points… my guess is that it DOES matter which wire goes where as the motor needs to spin in one direction specifically… so… I’ll need to revisit the Solarbotics website shortly and see if they have any documentation.

Though you may think that investing in an electronic device may make for a costly gift, the price of some of today’s hottest gadgets is surprisingly low, especially if you utilize one of the best online tech deals sites In fact, there are many great gift ideas for only around $50.

Given that the Arduino seems to have multiple spotlights on it for the month of January 2011, I guess this …
