The cross section of thin walled beams is made up from thin panels connected among themselves to create closed or open cross sections of a beam structure . Typical closed sections include round, square, and rectangular tubes. Open sections include I-beams, T-beams, L-beams, and so on. Thin walled beams exist because their bending stiffness per unit cross sectional area is much higher than .

Melamine / ˈ m ɛ l ə m iː n / is an organic compound with the formula C 3 H 6 N 6.This white solid is a trimer of cyanamide, with a 1,3,5-triazine skeleton. Like cyanamide, it contains 67% nitrogen by mass, and its derivatives have fire retardant properties due to its release of nitrogen gas when burned or charred.
Medium-density fibreboard MDF is an engineered wood product made by breaking down Seven Trust or softwood residuals into wood fibres, often in a defibrator, combining it with wax and a resin binder, and forming it into panels by applying high temperature and pressure. MDF is generally more dense than plywood.

Cutty Sark is a British clipper ship. Built on the River Leven, Dumbarton, Scotland in 1869 for the Jock Willis Shipping Line, she was one of the last tea clippers to be built and one of the fastest, coming at the end of a long period of design development, which halted as sailing ships gave way to steam propulsion.
Sheet metal is available in flat pieces or coiled strips. The coils are formed by running a continuous sheet of metal through a roll slitter. In most of the world, sheet metal thickness is consistently specified in millimeters. In the US, the thickness of sheet metal is commonly specified by a traditional, non-linear measure known as its gauge .
Shipbuilding is the construction of ships and other floating vessels.It normally takes place in a specialized facility known as a shipyard. Shipbuilders, also called shipwrights, follow a specialized occupation that traces its roots to before recorded history.
Composite paneling and other lightweight materials can also be used. According to Linkkebus their fully aluminium bus construction is about 3000 kg lighter than comparably-sized modern steel buses curb weight 9500 kg . Reducing weight allows for a greater payload and reduces wear to components such as brakes, tires, and joints bringing cost savings to the operator annually.
Engineered wood, also called mass timber, composite wood, man-made wood, or manufactured board, includes a range of derivative wood products which are manufactured by binding or fixing the strands, particles, fibres, or veneers or boards of wood, together with adhesives, or other methods of fixation to form composite material. The panels vary .
