@Asker As you can see from Marco's link (which is highly likely to be irrelevant to your context), "pleine masse" can have different meanings according to context. What are these "plateaux"? What are they made of? If they are wooden platforms for household appliances to stand on, then I'd go with Ana's answer.

More context required Please post the complete phrase! What does the phrase refer to? Furniture (what?), Household appliances (which type?). Carpentry?

To Asker Have you seen this? Is it of any help?
