The specification for a metal seal used with 1 1/4" (1.25 inch) steel strapping
which typically includes details about the material, dimensions, and performance requirements.
Below is a general outline of the specifications for such a metal seal: 1. Material:
Type: Typically made from stainless steel or galvanized steel for corrosion resistance.
Grade: Stainless steel (e.g., 304 or 316) or carbon steel with a protective coating (e.g., zinc plating).
2. Dimensions:
Width: Matches the width of the steel strapping, which is 1 1/4" (1.25 inches or 31.75 mm).
Length: Usually around 1.5" to 2" (38 mm to 50 mm) to provide sufficient overlap and strength.
Thickness: Typically ranges from 0.020" to 0.040" (0.5 mm to 1 mm), depending on the required strength and application.
3. Design:
Shape: Rectangular with rounded or chamfered edges to prevent injury and facilitate handling.
Sealing Mechanism: Designed to interlock with the steel strapping, often featuring teeth or serrations to grip the strapping securely.
Holes or Slots: May include holes or slots to allow for the insertion of a sealing tool or to accommodate different strapping tools.
4. Performance Requirements:
Tensile Strength: Must withstand the tensile strength of the steel strapping, typically ranging from 5,000 to 15,000 lbs (2,268 to 6,804 kg) depending on the strapping grade.
Shear Strength: Should resist shearing forces that could cause the seal to fail under load.
Corrosion Resistance: Must resist corrosion, especially if used in outdoor or marine environments.
5. Compliance:
Standards: Should comply with relevant industry standards, such as ASTM D3950 (Standard Specification for Strapping, Flat Steel and Seals) or other applicable standards.
Certifications: May require certifications for specific applications, such as food-grade stainless steel for use in food processing environments.
6. Application:
Usage: Designed for use with 1 1/4" steel strapping in applications such as bundling, palletizing, and securing heavy loads.
Tools: Compatible with standard steel strapping tools, including tensioners and sealers.
7. Packaging:
Quantity: Typically sold in bulk, such as boxes of 100 or 250 seals.
Packaging Material: Usually packed in cardboard boxes or plastic bags to prevent damage and corrosion.
8. Marking:
Identification: May include markings such as the manufacturer's logo, size, or material grade for traceability.
Example Specification Summary:
