Formatting integers in strings

I seem to be having a brain infarction and cannot see past this simple problem. I would like to be able to format a series of integers so that they are padded to the left with zeros as in: {000,030,060,090,120,150,180} Of course, I can write my own function to do this, but I want to use Mathematica's native formatting functionality. Here is my first try: NumberForm[Range[0,180,30],3,NumberPadding->{"0",""}] yielding: {0000,0030,0060,0090,0120,0150,0180} Making the obvious change: NumberForm[Range[0,180,30],2,NumberPadding->{"0",""}] yields: {000,030,060,090,0120,0150,0180} I have looked at the documentation for NumberForm and PaddedForm and there is no help there for this problem. Every example involves floating point numbers or integers that are not padded to the left. I am sure there is some simple concept that I am missing.
