Weber Genesis SP-435 Gas Barbecue (LPG)

The Weber Genesis SP-435 Gas Barbecue (LPG) is made for outdoor cooks who want premium power, smarter control and the confidence to cook for a crowd. This model sits at the top end of the Genesis line-up in a stainless steel finish that looks the part in modern alfresco spaces — and backs it up with features you’ll actually use every time you cook.

Running on LPG gives you flexibility: set it up where you want it, store a spare cylinder, and keep the barbecue ready for everything from quick weeknight meals to full-scale weekend entertaining.

Four burners + a dedicated Sear Zone that means business

A premium barbecue should do two things brilliantly: sear hard and cook evenly. The Genesis SP-435 is designed for both, with a dedicated ultra-hot Sear Zone powered by 2 Boost burners that deliver a serious hit of heat right where you want it.

That translates to:

• a proper crust on steaks and lamb

• deep colour on chicken thighs and wings

• smash burgers with real edge and bite

• prawns, skewers and fast seafood with minimal overcooking

Because the Sear Zone is a dedicated high-heat area, you can sear on the hot zone while running a steadier temperature across the rest of the grill — ideal for finishing, roasting, or holding food for serving.

PureBlu™ burners for even heat and repeatable results

The SP-435 uses PureBlu™ burners engineered to keep gas pressure consistent and distribute heat more evenly. The benefit is simple: your cooking becomes more predictable. You spend less time chasing hot spots and more time actually enjoying the cook-up.

Matched with porcelain-enamelled cast-iron cooking grills, the Genesis SP-435 heats up quickly, holds heat well, and delivers flavourful browning — the kind of performance you feel immediately when you’re cooking at higher temperatures.

Weber Crafted® versatility, with a griddle included

This isn’t a “grill-only” barbecue. The Genesis SP-435 is Weber Crafted® compatible, and it includes a Weber Crafted® griddle so you can jump straight into hot-plate style cooking.

The griddle is a game-changer for foods that are hard to do well on open grills, like:

• smashed burgers and toasted buns

• breakfast cooks (bacon, eggs, hash browns)

• fajitas, onions and mushrooms

• delicate foods you want to keep contained

It turns your barbecue into a broader outdoor cooking station — more variety, more menu options, fewer trips back to the kitchen.

Side burner: the secret to complete meals outdoors

The integrated side burner is where the SP-435 starts to feel like a true outdoor kitchen. Warm sauces, sauté veg, boil corn, reduce a glaze, or keep sides hot while the main cook happens on the grill.

It’s a simple add-on that makes entertaining smoother — and helps keep everything outside where the action is.

Storage and night cooking upgrades you’ll genuinely use

Premium barbecues aren’t only about power — they’re about workflow. The SP-435 includes thoughtful upgrades that make cooking easier and tidier:

• Grill locker storage under the side table to keep tools and accessories organised

• Nightvision™ LED handle lighting to illuminate the cooking area and side tables when the lid is lifted

• Weber Works™ compatibility on the side rails and side table so you can add snap-on and drop-in accessories (sold separately)

• Tank scale inside the cabinet to help monitor fuel levels so you’re not guessing mid-cook

• Grease management system with easy access for simpler clean-up

When you barbecue often, these practical features add up to a better experience — less mess, less scrambling, and more control.

LPG setup notes (important)

This model is designed for LPG (refillable cylinder). The cylinder is typically not included, so you can choose your preferred bottle and swap system. Many users keep a spare cylinder ready to go for uninterrupted cooking during busy seasons.
