FAQ 

Q1: What is the measurement accuracy of this level ruler?

A: The measurement error rate is guaranteed to be below 0.1% (equivalent to approx. 1.0mm/m or 0.5mm/m high-precision standard).

Q2: Why is cast aluminum better for masonry work than standard box levels?

A: Cast aluminum is solid and heavy-duty, making it much more resistant to heavy impacts, accidental drops, and concrete trowel taps without bending or losing accuracy.

Q3: Is the black epoxy coating resistant to wet cement and chemicals?

A: Yes! The specialized epoxy powder coating creates a smooth barrier that prevents wet mortar from sticking and protects the metal against chemical corrosion.

Q4: What sizes are available in this C-type level series?

A: We offer five standard sizes: 400mm, 500mm, 600mm, 800mm, and 1000mm.

Q5: What is the Minimum Order Quantity (MOQ) for custom OEM orders?

A: Our standard OEM MOQ for customized coating colors and branded packaging is 1,000 pcs per size (negotiable for multi-size order combinations).
