Could you pls answer my question?
What is the difference between these two statements:
-We are a company specialized in supplying...
-We are a company specializing in supplying...
This means you already have expertise in supplying something.
We are a company specializing in supplying...
You are still picking up the expertise in that supply trade.
In short, the first one means you are a skilled supplier, whereas the second one shows you are gradually gaining expertise in that field. If you are already an expert, use the first one.
Can I suggest
"We are a company that specializes in..."?
"We are specialists in..."
"We specialize in..."
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
