ProTop - 36"x48" - Welding Table

The Certiflat ProTop Welding Table - This welding table is designed specifically for welders, and is the same tables used in our shop daily and by OEM manufacturers across the USA and Canada. These kits are built with 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 building stiff, accurate welding fixtures has been proven in real-world manufacturing settings for over 15 years.


Dimensions: 36" x 48" Welding Surface - 1,728 Sq. Inches of usable surface area.

  • Integrates with the Heavy Duty Leg Kit - PN:LK3648-U-K
    • Sold Separately
  • Engineered tab & slot stiffening ribs for a guaranteed flat surface.
  • Proprietary "Heat Control Design" to eliminate warping during assembly.
  • High precision with +/- .003" on all parts included in the kit.
  • 16mm holes on 2" centers work with most fixturing clamps. 
  • Flat to +/- .015" per 12 inches when assembled according to instructions.
  • Specially designed weld points put the heat in the middle of the tabs and eliminate weld pull.

Our CNC sheet laser parts go together fast and square, using the tab and slot methodology throughout to make building a quality tool that lasts forever as simple as possible. The internal webbing works to force the table flat during assembly and keeps it that way for years of trouble-free and accurate welding. The 16mm holes on 2" centers fit most industry standard welding clamps and allow for infinite fixturing positions. Unlike other welding tables, our tops are designed and manufactured to ensure they're flat from the beginning and stay that way for the life of the tool.

Follow our assembly instructions and we guarantee your new welding table will be flat.

Note: The FabBlock and mini-block have sides with our standard hole pattern, and can be expanded by either using our fabwings or by bolting multiple blocks together. The options for sizes and configurations are essentially endless with the Mini-Block and FabBlock style tables!


  • The pro tables use one of the heavy duty leg kits.
  • Mini-Blocks, FabBlocks, and plasma tables use our FabRack.
    • The FabRacks can be purchased with or without casters.


  • We do not offer the pro table in thicker material. Due to the rib structure design, they are limited in size (largest 3x4) and thickness.


  • Threaded holes are very convenient for bolting your fixtures or our accessories to the table. Threaded holes are the quickest way to set things up on the table.
  • When you order threaded holes, the sides of the table will have the threaded pattern as well.
  • Pro tables are not available with threaded holes as there is not enough material. To attach accessories to the pro tables you would want to use parts FBN-2 and FBS-2, the fabnut and fabnut locating spacer washer.


  • We do have a 4-pack of squares available at a discount, parts VFS-2 and VFS-4. All other accessories are a la carte.


  • Fabnuts are threaded and have an o-ring. They insert into the 16MM hole from the underside of the table and are held in place by the o-ring.
  • The fabspacer fits in the 16MM holes on our accessories and allow you to get accurate placement with a 3/8-16 bolt.


  • We do offer in house assembly by our pro welders. The cost depends on the size of table or accessory.
  • For rates contact


  • It depends on our workload, currently about 4-6 weeks to ship on all tables except ProTops.

    Well built, much heavier than expected. Smooth assembly

    Item arrived quickly. Slightly disappointed as one corner was crushed/bent in about an inch from some kind of hard impact. Was able to clamp together, tack as per the video instructions, and weld together. Total time Start to finish about 4-hours. For a "garage fabricator" this table is perfect. Except for the damage, I am pleased with the item.

    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.
