When a brand owner designs a gas hob, the burner head gets most of the attention. But the part the customer touches first is the pan support — the grate the cookware rests on. If the grate and the burner head do not match, you get wobbly pots, unstable flames, and complaints. Here is why burner-to-grate matching matters for OEM.
The pan support sits over the burner head and holds the cookware at the correct height above the flame. Three things must line up: the grate's opening must clear the burner cap, the height must position the cookware in the flame's sweet spot, and the footprint must sit stable on the hob plate.
If the grate holds the pot too high, heat is lost to the air. Too low, and the flame is choked, producing soot and wasted gas. The correct burner-to-grate height — determined by the burner cap profile, whether glossy flat or concave — is what gives clean, efficient combustion.
The cap finish and shape matter here. A concave cap concentrates the flame toward the center, which changes the ideal grate height and pot support. A flat cap spreads the flame wider. Your grate design must be tuned to the cap profile you choose.
The best OEM results come from treating the burner, cap, and grate as one matched system, not separate parts. THREEMI manufactures SABAF-compatible burner heads in sizes #130/#100/#75/#55 with glossy flat, glossy concave, and matte flat finishes — and we can coordinate burner, cap, and pan support geometry so your hob performs and feels right.
