Leon Hunt set up the business in 2000, after several years working at a large supplier of road traffic signs.
"Frankly, just selling aluminium panels wouldn't be difficult, but supplying the sign trade is much more than just selling," says Leon.
"For one thing, consistently high quality is crucial. Many customers are smaller businesses and those placing the orders are likely to be the people that will be facing up the product, so there's no hiding if the quality isn't up to the mark. I know what it's like to not work with the best so I make sure the material is up to the job, every time. In addition, having been in the trade for years, I know the other difficulties sign makers come up against."
DLM buys in large quantities of metal from stockholders and fabricates its products at 2300 sq.ft. premises in York. In-house equipment includes saws, press brake, guillotines, and flush finish riveting machine, as well as aluminium, stainless and mild steel welding facilities.
Leon adds: "With all the equipment and experience at DLM, we rarely get an enquiry for anything that we aren't able to fabricate in-house."
The company's popular flat aluminium blanks are manufactured from 2.85 mm pre-treated aluminium with a grey powder coating on the rear, offering corrosion resistance and a long life for both internal and external signage.
DLM cuts flat panels to any size and laser profiles to any shape required, supplying mill finish or powder coated to most standard RAL or BS colours. Flat aluminium panels can be supplied with square or radius corners, with or without pre-punched holes for wall mounting, with or without fixing channel on the rear for post or wall mounting, and edges can be folded with returns to give the option of post fixing inboard or outside the sign.
A flush rivet system is used to attach fixing channels to the rear of blanks, meaning that when vinyl or graphics are applied to the panel face there are no protruding rivet heads. Powder coated blanks with a grey reverse and white powder coated face and white head rivets are especially popular.
"There are no pop rivets and double sided tape isn't needed. The white powder coating gives a very smooth finish and because many road signs are black text on white, it saves having to apply white vinyl," says Leon.
Another established favourite with DLM customers is aluminium composite material. This can be riveted in the same way using flush finish rivets, with or without radius corners and can also be profiled cut to shape. Also popular with businesses making road traffic signs are blanks with alochromed face, which provides a particularly good key for vinyl application.
