What is the difference between side mount and undermount drawer slides?

Side mount slides fix to the drawer sides and cabinet walls — easy to fit and tolerant of cabinet tolerances. Undermount slides sit beneath the drawer box, hide the hardware for a cleaner look, and need a compatible drawer box with the right reveal. AOLISHENG builds both: side-mount heavy-duty series (2053 / 2576 / 7625) and undermount soft-close series (MK316 / U4510K).

What does full extension mean compared with 3/4 extension?

3/4 extension leaves the back of the drawer still inside the cabinet; full extension brings the whole drawer clear of the cabinet face so you can reach the back corner. Most AOLISHENG heavy-duty and soft-close series are full extension.

How do I choose the load rating for a drawer slide?

Add the heaviest realistic contents, then add 25–30% headroom so the slide is not run at 100% of its rating every day. AOLISHENG ratings run from 100 lb (U1245) through 265 lb (2053 family), 330 lb (2071), 500 lb (2576 family) up to 770 lb (AQ7625K3 twin-slide).

What are soft-close drawer slides and when do I need them?

Soft-close slides use a damper that pulls the drawer shut in the last few centimetres, preventing slamming. They are most noticeable on kitchen and bathroom cabinetry and also reduce the shock load that gradually loosens a carcass. AOLISHENG soft-close options include K2053, U4510K and MK316.

Are stainless steel slides worth it for outdoor or marine use?

Yes — whenever the slide is exposed to weather, salt air, humidity or frequent wash-down (outdoor kitchens, marine galleys, food-prep, coastal installs). AOLISHENG stainless options include W2053, W2576, W5115 and U4510K.

Which AOLISHENG series number maps to which spec?

The stamped codes read: 1245 = 100 lb stainless side mount; 4510 = 100 lb stainless; 5115 = 150 lb; 2053 = 265 lb; 2071 = 330 lb; 2576 = 500 lb; 7625 = 770 lb twin-slide. Remove the drawer and read the code on the inner rail, or send a photo and AOLISHENG will match it.

Can heavy-duty slides be used in RVs, trucks and vehicles?

Yes, with a locking slide so the drawer cannot slide open under braking or cornering. Use locking series such as D5115, D2053 or D7625 for any moving-vehicle storage.

Stainless Steel Drawer Slides: When (and Why) to Choose 304 Over Coated Steel

Why Stainless Steel Drawer Slides?

Most AOLISHENG drawer slides use cold-rolled steel with blue-zinc plating or black electrophoresis — durable for indoor cabinetry. But when a drawer lives outdoors, on a boat, in an RV, or anywhere humidity and salt air reach it, 304 stainless steel is the right call. Stainless resists rust and corrosion far better than coated carbon steel, so the drawers keep sliding smoothly for years.

Stainless vs Coated Carbon Steel — Which to Choose

Condition	Best choice	Why
Indoor kitchen / office / bathroom	Zinc-plated or electrophoresis carbon steel	Cost-effective, more than enough protection
Outdoor kitchen, BBQ island	304 stainless steel	Withstands rain, grease and temperature swings
Marine / boat / coastal	304 stainless steel	Salt air is the #1 cause of slide corrosion
RV / camper (constant vibration)	304 stainless + locking option	Corrosion + movement resistance in one
Industrial / warehouse (dry)	Carbon steel heavy-duty	Highest load per dollar

AOLISHENG Stainless-Steel Options

Several AOLISHENG families ship in a 304 stainless variant alongside the standard carbon-steel version:

2576 Series — up to 500 lb / 227 kg full-extension side-mount, with a stainless option for RV and outdoor kitchens.
7625 Series — 76 mm wide, 220 kg / 485 lb, offered in Q235 cold-rolled steel or 304 stainless steel.
5320 Series — 53 mm wide, 120 kg / 265 lb, available in stainless for humid environments.
4510 Series — 45 mm home & decor slide, 201 stainless option for light indoor use.

Care Tips for Long Life

Wipe stainless rails with a dry cloth; avoid steel wool that scratches the passive layer.
For coastal use, rinse occasionally with fresh water to remove salt residue.
Keep the ball-bearing raceways free of grit — a light silicone spray is enough.
