Stainless Steel · built from plate · Manor, Texas
Matterplay fabricates stainless built-up beams, channels, HSS, angles and WT from ASTM A240 plate, machine welded per AWS D1.6 and finished per ASTM A380. Every member is traceable by heat number and ships with certified reports for structural and miscellaneous uses.
“Each beam is fabricated from ASTM A240 stainless plate, welded per AWS D1.6, fully traceable by heat number, and delivered with certified reports to show structural strength and straightness.”
Plate specification: chromium and chromium-nickel stainless.
Structural welding code for stainless steel.
Every plate carries its mill heat; the MTR follows the member.
Structural performance and straightness certified by Matterplay.
W beams that are not produced by the hot-rolled mill are made from three plates, built up and welded together.
The heat number is transferred to the plates we cut.
Cut to appropriate size.
Flanges and web are squared and clamped on the fit table.
Continuous fillet welds at each flange-to-web junction, to AWS D1.6 stainless requirements.
Per ASTM A380.
Product inspected and shipped with Inspection Certificates.
The twelve questions engineers put to us first. One answer each.
A fillet weld can have equal or greater strength than a full-pen or laser-fused weld.
ASTM A240 plate, welded per AWS D1.6, straightness per ASTM A6 tolerances, finished in accordance with ASTM A380.
Beams: three plates, fillet-welded. WT: two plates, fillet-welded. HSS: two bent plates, welded together. Channels and angles: bent plate.
Calculations can be provided on area, moment of inertia, elastic and plastic section moduli, torsional constant and radius of gyration.
WPS, PQR and welder qualifications.
Engineers and owners have approved these fabrications several times before; we help with the documentation so approval does not delay the project.
Compared with laser-fused beams.
Standard sections, cut to the lengths and dimensions you need.
Specified, approved and installed on real projects.
Plate per ASTM A240. Welds per AWS D1.6. Straightness per ASTM A6. Finish per ASTM A380.
They will come to you straight and squared.
Cost-effective and budget-friendly.
The structural engineering community already accepts welded built-up members.
Fillet weld vs. full-pen / laser-fused
Every beam we build has a continuous fillet weld on each side of the web, at every flange-to-web junction.

A Matterplay fillet-welded built-up member provides equal straightness and finish and equal or greater strength, at lower cost.
Specify the section you need, and we back it with the numbers and the paperwork.
Stainless built-up beam, channel, HSS, angle or WT.
Section properties and capacity for the member you need.
The documentation an EOR expects.
Equal or greater strength, at lower cost.
We’ll call you, send a sample, send calculations, or come see you. Whatever moves the relationship forward.
