M4 Trailers has grown over the years into a well-established company that prides itself on producing first-class products.
We pay great attention to detail from the design stage right through to the manufacture of the finished products.
Both M4 Trailers and our sister company Phillip Rees Welding Ltd are based in South Wales. Owner Phillip Rees has an in-depth understanding of the farming industry. With this knowledge we’re able to provide an unbeatable service to farmers, from the supply of agricultural trailers and equipment, to repairs and refurbishment facilities, and the design, supply and erection of farm buildings.
