Zinc Drywall Screws Series
Zinc Coated Drywall Screws
1/2 Drywall Screws (13MM Drywall Screws) are short-size drywall screws designed for thin gypsum boards and special scenarios. They are suitable for thin gypsum boards (1/4 inch or 3/8 inch thick). They ensure that they penetrate the board surface and embed 5-8 mm into the keel or substrate to avoid excessive penetration and damage to the back structure
Zinc Plated Drywall Screws （Yellow）
1-1/2 inch plasterboard screws (38mm plasterboard screws) are designed for thin and light boards and precision construction scenes. After penetrating the board, they are only embedded in the wooden keel or metal frame by 3-5 mm, while maintaining 7-10 pounds of pull-out force to ensure the effective bite strength of the thread, especially suitable for scenes that are sensitive to depth, such as suspended ceilings and partitions.
Galvanised Collated Screws
2 Drywall screws (50MM Drywall Screws) are the most perfect size in the decoration field.Balance of depth and strength: 2-inch length can penetrate the standard 12.7mm gypsum board and fully embed into the wood structure or metal keel, ensuring that the thread engagement depth is more than 15mm, avoiding the risk of loosening due to being too short or penetration caused by being too long.

Advantages of Galvanized Drywall Screw
Galvanized anti-rust:
The surface is electroplated with zinc (the thickness of the zinc layer is 4-8μm), which can form a dense protective layer on the surface, effectively isolating water vapor, salt spray and chemical corrosion. The corrosion resistance is far superior to ordinary screws, which can extend the service life.
Efficient design:
Self-tapping pointed head: No need to pre-drill holes, easily penetrate gypsum board, metal or wooden structure.
Fine thread + deep groove: Enhance the bite force, prevent loosening, and ensure that the board is flat and without bulges.
Versatile adaptation:
Compatible with a variety of frame materials such as wood and light steel keels, with strong versatility.
Durable material:
Made of high-strength carbon steel, with high hardness, bending resistance, and excellent load-bearing performance.
High cost-effectiveness
The unit price is slightly higher than phosphated drywall screws, but it saves maintenance costs in the long term and reduces the frequent replacement of rust
Sinsun’s warranty support: The brand provides an 18-month warranty, free replacement for non-artificial damage, and reduces user risks.
Main Uses Of Galvanized Drywall Screws
Gypsum board installation: fix gypsum board to metal/wooden keels, used for walls, ceilings, partitions, etc.
Metal frame: connection of light steel keels and steel frame structures, such as suspended ceilings and partitions.
Outdoor projects: outdoor structures that need to be rust-proof, such as rain shelters and fences (it is recommended to be used with waterproof coating).
Renovation and maintenance: replace rusty or aged screws and repair loose boards.
Galvanized VS Black Drywall Screws
| Comparison item | Black Drywall Screws | Galvanized Drywall Screw |
| Rust resistance | Only suitable for dry indoor environments Resistant to moisture and salt sp | suitable for indoor and outdoor use |
| Service life | 1-3 years (easy to oxidize and rust | More than 5 years (galvanized layer protection |
| Construction efficiency | Need to control humidity, easy to jam Strong self-tapp | suitable for high-speed power tools |
| Maintenance cost | Frequent replacement of rusted screw | Almost maintenance-free |
Recommendations For Use
Tool matching: It is recommended to use an electric screwdriver (speed ≤ 3000 RPM) with a magnetic bit to improve efficiency.
Installation spacing: The screw spacing at the edge of the gypsum board is ≤ 15cm, and the middle area is ≤ 30cm.
Avoid over-tightening: The screw head should be slightly embedded in the paper surface to avoid tearing the surface of the gypsum board.
Safety protection: Wear goggles and gloves during operation to prevent debris from splashing.
FAQ
Q1: Are galvanized screws completely waterproof?
A1: The galvanized layer provides basic rust prevention. It is recommended to use with sealant when exposed to rain or salt spray for a long time.
Q2: Can galvanized drywall screws be used for load-bearing beams or structural supports?
A2:Only for non-load-bearing structures. Structural bolts or engineering screws are required for load-bearing parts.
Q3: What is the difference between galvanized and ordinary drywall screws?
A3: Ordinary screws are mostly phosphated and have weak rust resistance; galvanized screws have a longer life and are suitable for humid areas.
