A spokesman said not all the timber had come ashore and a large amount could still be drifting in the sea.
Kent Police have warned people not to remove any timber from the shoreline but coastguards said there had been reports of people trying to collect the wood.
Alison Kentuck, Receiver of Wreck, said: "The timber is not suitable for building material, it is saturated with salt water.
"The simple message is, it is not a case of finders keepers. The timber does have an owner and that is not likely to be the person picking it up off the beach.
"They must by law report all of their recoveries to the receiver and it is a criminal offence if they fail to do so."
'Dangerous place'
Many people also gathered on the beach in Ramsgate throughout the day to view and take pictures of the piles of timber.
Ivor Woods, 53, of Kent Terrace, Ramsgate, added: "It's a talking point in our small town.
"It's quite surprising the amount that has been washed up and the artistic way it has fallen into piles. There are quite a few photographers here taking shots."
Ch Supt John Molloy said: "We are working with the coastguard and our partner agencies to make the beaches safe.
"I would like to remind people that the shoreline can be a dangerous place, particularly with the current poor weather and people could be putting themselves at unnecessary risk by venturing into the sea to salvage the timber.
"This cargo remains the property of the original owner and to steal it is not only foolhardy, but also a criminal offence."
He added: "Whilst I appreciate that this sight is not commonplace and people may wish to take a look, we ask that they do this from a safe distance and leave the timber alone."
Anyone who wants to visit the shore has been asked to park considerately so that emergency access to the area remains open.
