A hangar is a closed building structure to hold aircraft, spacecraft or tanks in protective storage. Most hangars are built of metal, but other materials such as wood and concrete are also used. The word hangar comes from Middle French hanghart ("enclosure near a house"), of Germanic origin.

Hangars are used for protection from the weather, direct sunlight, maintenance, repair, manufacture, assembly and storage of aircraft on airfields, aircraft carriers and ships.

Steel construction is well placed to satisfy all the requirements of good car park design. Steel is:

• Ideal for long spans – providing column-free parking space
• Lightweight – reducing foundation requirements
• Robust and fire resistant
• Fast in construction – particularly relevant where the venue that is to be served is to remain operational during construction, e.g. retail, stations and hospitals
• Easily maintained
• Vandal resistant
• Modular steel systems are available for demountable structures
• Economic.

Steel construction also has many generic benefits that are relevant to car park buildings.

Steel is widely used around the world for the construction of bridges from the very large to the very small. It is a versatile and effective material that provides efficient and sustainable solutions. Steel has long been recognised as the economic option for a range of bridges. It dominates the markets for long span bridges, railway bridges, footbridges, and medium span highway bridges. It is now increasingly the choice for shorter span highway structures as well. Society gains in many ways from the benefits delivered by steel bridge solutions. Landmark steel bridges embody good design, they are fast to build, and have stimulated the regeneration of many former industrial, dock and canalside areas.

School buildings must withstand a considerable amount of wear and tear on a daily basis and still be functional for many years of use. Investing in a steel building from General Steel is the most prudent decision for durability and structural strength. Not to mention, all of our buildings come with a 50 year structural warranty standard. Made from only the highest quality materials, a new school building from General Steel will withstand the elements while saving both your school, and your community.

Retail buildings are of five basic types; down-town shopping centres, single storey supermarkets, warehouse-type distribution centres , mixed use retail and commercial/residential buildings in which the retail units generally occupy the ground floor and superstores. The retail sector is very competitive and therefore the attributes of steel construction to deliver flexible, lightweight solutions fast and cost effectively makes steel the material of choice for the sector.

Customer experience is paramount in retail buildings. Using steel construction, retail floor plans are maximised giving retailers the maximum scope to configure store layouts to maximise sales to their targeted customers.

Many retailers, particularly supermarkets, are owner occupiers and therefore, unlike some other commercial sectors, they have a greater interest in whole life cost and added value through sustainable design. Consequently, the retail sector is leading in the procurement of sustainable, low carbon buildings.

A factory (previously manufactory) or manufacturing plant is an industrial site, usually consisting of buildings and machinery, or more commonly a complex having several buildings, where workers manufacture goods or operate machines processing one product into another.

Factories arose with the introduction of machinery during the Industrial Revolution when the capital and space requirements became too great for cottage industry or workshops. Early factories that contained small amounts of machinery, such as one or two spinning mules, and fewer than a dozen workers have been called "glorified workshops".

Most modern factories have large warehouses or warehouse-like facilities that contain heavy equipment used for assembly line production. Large factories tend to be located with access to multiple modes of transportation, with some having rail, highway and water loading and unloading facilities.

A warehouse is a commercial building for storage of goods. Warehouses are used by manufacturers, importers, exporters, wholesalers, transport businesses, customs, etc. They are usually large plain buildings in industrial areas of cities, towns and villages.

They usually have loading docks to load and unload goods from trucks. Sometimes warehouses are designed for the loading and unloading of goods directly from railways, airports, or seaports. They often have cranes and forklifts for moving goods, which are usually placed on ISO standard pallets loaded into pallet racks. Stored goods can include any raw materials, packing materials, spare parts, components, or finished goods associated with agriculture, manufacturing and production. In Indian English a warehouse may be referred to as a godown.

A residence is an establishment where it was originally or currently being used by a host as their main place of dwelling or home. Architecturally, a residence is typically a house, mansion, cottage or grand castles and palaces. A residence is offered to travelers as temporary lodgings where they can rent a room. The rooms are generally furnished in the style which complements the architecture type of the building. This boutique type of accommodation has a nice homely feel where the traveler is the 'house-guest'. Hotels, especially the extended stay chains, commonly function as residences for many guests
