Aveling and Porter was a British agricultural engine and steamroller (road roller) manufacturer. Thomas Aveling and Richard Thomas Porter entered into partnership in 1862, and developed a steam engine three years later in 1865. By the early 1900s, the company had become the largest manufacturer of steamrollers (road rollers) in the world. The company used a rampant horse as its logo derived from the White Horse of Kent.
Aveling & Porter built more steam rollers than all the other British manufacturers combined. They also built traction engines and steam wagons.[36] Just under 600 of the company’s various steam engines survived to enter preservation.
Another example of Aveling and Porters engineering skills can be seen in the massive covered slips at Chatham Dockyard. These Leviathans pre-date the great London train sheds of St. Pancras, King's Cross and Paddington—traditionally understood to be the oldest and largest metal framed structures of the time.

The company was founded in 1856 by Arthur Wallis and Charles Haslam in newly built premises which they named The North Hants Ironworks. The works were sited on Station Hill in Basingstoke and the company began trading as Wallis & Haslam. Shortly afterwards the company was highly commended for its hand-worked bench drilling machine at the 1857 Royal Agricultural show in Salisbury. Even at this early stage, the company was producing a wide variety of agricultural equipment, and alongside the bench drill were corn drills, turnip drills, four types of horse hoe, drag harrows, a 3 hp threshing machine, a barley hummeller and sundry other devices. In 1862 a third partner, Charles James Steevens, joined the company and when Charles Haslam retired in 1869 the company became Wallis & Steevens.
