Frequently Asked Questions
Solid screw jacks (26-48mm) are ideal for medium to heavy loads and are typically cast. Hollow screw jacks (34mm+) are drop-forged, offering a better strength-to-weight ratio for heavy-duty industrial applications.
Swivel jacks feature a pivoting base that allows the jack to tilt, ensuring the scaffolding remains vertical and stable even when the ground surface is uneven or sloped.
Hot-dip galvanizing is highly recommended for coastal or high-humidity areas as it provides the thickest and most durable layer of corrosion protection.
Our U-Head jacks are designed to secure a wide variety of wooden beams; however, we recommend matching the beam width to the U-Head size (available 30mm to 48mm) for maximum stability.
We utilize high-precision machinery for casting and forging, combined with a rigorous mold maintenance program to ensure every thread is consistent and operates smoothly.
We use specialized steel pallets and secure wrapping to maximize the internal volume of 20-foot containers, ensuring maximum product quantity per shipment while preventing damage.
