About Us

About Us

The old Hightech Signs Inc. served Rockwall and Mesquite for decades, and when that family business retired, we opened the new Sigma Graphics (dba Rockwall Hightech Signs) in the same location, to continue serving those loyal customers.  Our art files go back to 1995, so whether you’re ready for a reprint, or want to freshen up your look with a new design – we can help!

Our Mission:
We Grow Your Business

A good sign pays for itself, but a great sign company helps you get the best return on your graphics investment. Turn that vehicle into a moving billboard that’s working for you 24/7. Or turn those blueprints into a sign package that WOWs your client: on schedule and below budget.

Focus on B2B

We specialize in corporate accounts, contractor solutions, advertising wraps, and business logos on buildings, monuments, and pylons. Although we are capable of consumer graphics, we’ve chosen to strictly focus business to business sales.

After all, there are great sites online that ship custom graphics for gifts and decor; or industry-specific sites with razor sharp pricing for just realtors, car dealerships, etc.  But when you’re launching a new business, or getting new graphics for your vehicles, you should be able to meet face-to-face with a sign expert who is laser focused on your success – who understands your goals, and gets you on that road asap.
