Certiflat 36"X48" Heavy Duty Welding Table

Look How Easy It Is To Build A Quality Tool That Will Last A Lifetime


CertiFlat's PRO Series welding table top kits were designed from the ground up, with the welder in mind. These are the exact same tables we use in our shop daily. In addition they are in use by dozens of OEM manufacturers across the USA and Canada. Pro Series Table Kits are build from tough 3/16" Hot Rolled Pickled & Oiled Steel using state of the art CNC Laser Cutting technology for an exceptional fit-up.

Our proprietary Tab & Slot methodology for build stiff, accurate welding fixture has been proven in real world manufacturing settings for over 15 years. We design and build welding fixtures for every Power-sports OEM in the US. If you're riding an ATV the was sold in this country in the last ten years; there's probably weldments on it that came out of our Tab & Slot fixtures! We are work holding specialists.

All CertiFlat PRO Series Table Top Kits Feature:

  • Engineered Tab & Slot stiffening ribs for a guaranteed flat surface.

  • Proprietary  "Heat Control Design" to eliminate warping during assembly. 

  • +/- .003" on all parts included with your kit. Very high precision.

  • 16MM holes on 2" centers work with Strong brand tools as well as others

  • CNC Laser Cutting of all components. OUR PARTS FIT!

  • No Questions Asked refund policy. If you're not happy, we're not happy.

  • Table top kit only to allow you to customize the mounting as you see f

  • GUARANTEED FLAT! to +/- .015" when assembled according to our instructions

  • Integrates with the Heavy Duty Leg Kit part # LK3648-U-K

Unlike other so called welding tables, our tops are designed and manufactured with tab and slot webbing on the bottom to ensure they're flat from the beginning and stay that way for the life of the tool. Other kits and tables, if you can call them that; listed online are just a piece of sheet metal with holes in it and comes curled up like a taco shell right out of the box. 

CNC Sheet Laser Parts go together fast and square. Tab and Slot Methodology is used throughout to make it brain dead simple to build a quality tool that lasts forever. Internal webbing forces the table flat during assembly and keeps it that way for years of trouble free and accurate welding. 16MM holes on 2" centers fit all Strong brand clamp and tools, and allow for infinite fixture positions. Unique Tab and Slot webbing design forces the top flat during assembly. Specially designed weld points put the heat in the middle of the tops and eliminate weld pull. By following the proper sequence (shown in easy to understand step by step instructions & video) we assemble these tops daily flat to +/- .010"with no special tools. Follow our instructions and we will guarantee your new table is flat.

Happy welding.

    I’m loving this table

    The table was easy to put together. I built my own leg kit with 5 inch lockable casters. I love how easy it has made my fabrication.

    3’x4’ PRO Top weld table

    I really enjoy having a table that is precision cut from a laser. The holes on the top make everything perfectly square. During assembly, the tab and slots are perfectly laser cut making assembly fast. Customer service is a 5 star. I would give them a six if I could. I called them with a problem with my welding top and they were very kind and helpful. Shipping was super fast. I made my order and within two days received my table top. If I could do it again, the only thing I would do different is I would buy a lager and thicker top. The PRO top fit my budget, but I should have gone bigger for the jobs I do in the shop.

    Certiflat 3 X 4 table

    This is an excellent weld table. The material is top quality, and the fit of the parts excellent. There are a multitude of videos online that show how to assemble the table and keep it flat, so follow those to see how to assemble it properly and you will have a great result. I left out one of lower crossbars on the legs, so that I can sit at the table and not hit my shins on the crossbar, and have my pedal under the table. This has not in any way affected stability of rigidity negatively. This is a great table for the amateur or hobbyist - it is not an industrial precision table, and doesn't have the price tag of one either. It is a high quality made in America product, ideal for light duty fabrication. The team at CertiFlat were great to work with and very helpful when I picked the table up in person. I am very glad I bought one of these rather than an import version - this will last a life time for sure.

    Easier then expected

    To be honest I don’t have it all together yet. I was very surprised it was assembled and framed together, and all I had to do was flatten and clamp it down. Underpromise and over deliver is not a bad business structure to have and people take notice of the small things it’s a thumbs up for me.
