Around 400 tonnes of scrap metal is affected by the fire.
Deputy Assistant Commissioner Richard Arnold, who is at the scene, said: "Crews are working hard to bring the fire at a scrap metal recycling yard under control. This will be a protracted incident, with firefighters expected to be on scene for most of the day.
"The fire is producing a significant amount of smoke in the vicinity, which is moving east towards Dartford.
"We strongly urge people who live or work nearby to keep windows and doors closed and avoid the area where possible."
One of the Brigade's 32-metre turntable ladders is being used at the scene as a water tower to tackle flames from height.
The Brigade's Control Officers took the first of 16 calls to the fire at 0456 and sent fire crews from Erith, Bexley, Plumstead, Sidcup and surrounding fire stations to the scene.
The cause of the fire is not known at this time.
