SL200 and SL100 are security-level ratings under AS 5039:2024, the Australian Standard for security doors and screens. From an occupant’s point of view, the main difference is the force each product must withstand during impact testing.
Key differences
- SL200: Withstands five impacts of 200 joules each in dynamic impact testing.
- SL100: Withstands five impacts of 100 joules each in dynamic impact testing. This rating is typical of traditional diamond-grille designs.

ClearShield products
The full range of ClearShield domestic and commercial products complies with SL200, having been tested and recertified to the new standard. No changes to the design or manufacturing process were needed. This means older products in the Ultrastrength range are also certified at the higher level, subject to the exception below.*
* Some Multi-door arrangements require retrofitting with new joining mullions to meet compliance.
