Overview
This Petkao 7538SS-13 is a replacement grill part measuring about 23.75 x 3.75 x 2 inches and weighing 11.43 lb, listed as a gas grill component rather than a full grill. The 7538 model number matches Weber's own part number for Genesis 300 series cooking grates, which is the compatibility this listing is built around.
Buyers shopping by Weber's OEM number will recognize 7538 as the stainless cooking grate set for the Genesis E-310, E-320, E-330, S-310, S-320 and S-330 grills. Petkao's version is a third-party replacement sized to that spec rather than an original Weber part, so fit should match those models specifically and not other Genesis generations.
- Matches Weber 7538 part number
- Stainless steel grate
- Fits Genesis 300 series (E-310/E-320/E-330, S-310/S-320/S-330)
- 11.43 lb
Who it's for
For Genesis 300 series owners whose original cooking grates have rusted or warped and need a same-spec stainless replacement without buying from Weber directly. Not the right part for other Genesis series, Spirit or Q line grills, which use different grate dimensions.
Strengths and trade-offs
Drawn from this product's published specifications.
- Sized to the Weber 7538 Genesis 300 series spec
- Stainless steel resists rust better than coated grates
- 4.5 star average from 127 reviews
- Only fits Genesis 300 series grills, not other Weber lines
- Third-party part, not genuine Weber
- Dimensions suggest a multi-piece set, confirm count before ordering
Performance notes
At 11.43 lb for a grate set sized 23.75 x 3.75 x 2 inches, these read as a multi-piece rectangular grate set rather than a single grate, consistent with how Weber's 300 series cooking area is divided. Stainless construction should resist rust better than the painted or porcelain coated grates some grills ship with, provided the alloy grade holds up over repeated heat cycles.
