BeeCastle Beeswax-Coated Plastic Foundation Sheets for Langstroth Deep Frames — 20-Pack, Pre-Waxed 16.65×8.26 in

BeeCastle's 20-pack beeswax-coated plastic foundation sheets provide ready-to-use, food-grade foundation that fits Langstroth deep frames and encourages clean comb building.

These foundation sheets are plastic cores coated with beeswax to combine the durability and straightness of plastic with the natural attraction of wax. Each sheet measures approximately 16.65 x 8.26 inches (42.2 x 20.98 cm), sized to fit standard deep Langstroth frames. Sold in a set of 20, they are intended for beekeepers who want uniform, reliable foundation for brood or honey comb without repeatedly molding wax by hand.

How do these coated foundations make frame setup faster?

Because the sheets are pre-coated with beeswax and sized to slip into grooved frames, they reduce the time needed to prepare frames for colonies. Installations are straightforward and require no additional waxing or reinforcement in most setups.

• Pre-waxed plastic core for immediate use.
• Slides into grooved top bars without extra support.
• Consistent sheet dimensions for uniform frame spacing.

Will these fit my Langstroth deep hive frames?

Yes—each foundation measures 16.65 x 8.26 inches, which matches common deep Langstroth frame dimensions so they sit correctly in the grooves. The sizing maintains correct comb placement and hive spacing when inserted properly.

• Exact dimensions: 16.65 x 8.26 in (42.2 x 20.98 cm).
• Designed specifically for deep frames used in Langstroth hives.
• Works with standard frame grooves and spacers.

What are the material benefits of plastic with beeswax coating?

The plastic base offers structural strength and long-term straightness, while the thin beeswax coating provides a natural scent and texture that bees readily accept. This hybrid approach reduces warping and makes comb removal and inspection simpler compared with pure wax foundations.

• Food-grade plastic core for durability and stability.
• Beeswax coating to attract bees and support cell building.
• Easier to handle during inspections and less prone to deformation.

How many sheets are included and what applications suit a 20-pack?

This kit contains 20 coated foundation sheets—enough to outfit several deep frames or replenish foundations across multiple hives. It's a practical quantity for hobbyists expanding apiaries or small-scale commercial keepers maintaining consistent brood and honey comb structure.

• Twenty sheets per pack for multiple frames or hives.
• Good balance between quantity and storage convenience.
• Useful for new frame builds, replacements, or routine maintenance.

Who is this for? Beekeepers who want reliable, ready-to-install foundation that combines the longevity of plastic with the natural appeal of beeswax will find these BeeCastle sheets useful. They're suited to backyard hobbyists, seasonal apiarists scaling up a few hives, and operators who prefer consistent, straight comb without repeated hand-dipping or casting. Avoid if you require pure natural wax foundation without a plastic core.
